* PDGF-A signaling is required for secondary alveolar septation and controls epithelial proliferation in the developing lung{{#pmid:29636361|PMID29636361}} "Platelet-derived growth factor A (PDGF-A) signaling through PDGF receptor α is essential for alveogenesis. Previous studies have shown that Pdgfa-/- mouse lungs have enlarged alveolar airspace with absence of secondary septation, both distinctive features of bronchopulmonary dysplasia. ...In the absence of PDGF-A, the number of PdgfraGFP+ cells was significantly decreased. In addition, proliferation of PdgfraGFP+ cells was reduced. During alveogenesis, PdgfraGFP+ myofibroblasts failed to form the α-smooth muscle actin rings necessary for alveolar secondary septation. These results indicate that PDGF-A signaling is involved in myofibroblast proliferation and migration." | |||

Introduction
The respiratory system does not carry out its physiological function (of gas exchange) until after birth. The respiratory tract, diaphragm and lungs do form early in embryonic development. The respiratory tract is divided anatomically into 2 main parts:
- upper respiratory tract, consisting of the nose, nasal cavity and the pharynx
- lower respiratory tract consisting of the larynx, trachea, bronchi and the lungs.
In the head/neck region, the pharynx forms a major arched cavity within the phrayngeal arches. The lungs go through 4 distinct histological phases of development and in late fetal development thyroid hormone, respiratory motions and amniotic fliud are thought to have a role in lung maturation. Branching is a key mechanism/process in lung development leading to alveolar saccules after about 23 branching generations (range of 18–30).
The two main respiratory cell types, squamous alveolar type 1 and alveolar type 2 (surfactant secreting), both arise from the same bi-potetial progenitor cell.[1] The third main cell type are macrophages (dust cells) that arise from blood monocyte cells.
Development of this system is not completed until the last weeks of Fetal development, just before birth. Therefore premature babies have difficulties associated with insufficient surfactant (end month 6 alveolar cells type 2 appear and begin to secrete surfactant).

Objectives
- Describe the development of the respiratory system from the endodermal and mesodermal components.
- Describe the main steps in the development of the lungs.
- Describe the development of the diaphragm and thoracic cavities.
- List the respiratory changes before and after birth.
- Describe the developmental aberrations responsible for the following malformations: tracheo - oesophageal fistula (T.O.F); oesphageal atresia; diaphragmatic hernia; lobar emphysema.
Development Overview
Week 4 - laryngotracheal groove forms on floor foregut.
Week 5 - left and right lung buds push into the pericardioperitoneal canals (primordia of pleural cavity)
Week 6 - descent of heart and lungs into thorax. Pleuroperitoneal foramen closes.
Week 7 - enlargement of liver stops descent of heart and lungs.
Month 3-6 - lungs appear glandular, end month 6 alveolar cells type 2 appear and begin to secrete surfactant.
Month 7 - respiratory bronchioles proliferate and end in alveolar ducts and sacs.
Mechanisms
- Initiation - Budding of foregut endoderm to generate the trachea.
- Branching - A repeated mechanism of branching that is ongoing throughout development to form the conducting bronchioles then alveolar ducts.
- Surface area increase - Expansion of the surface area in late development generating eventually the thin air–blood barrier for gas exchange in the acini.
- Vascular development - Extension of a vascular capillary tree within the connective tissue and wall of the acini for gas exchange, and the lymphatic development for immunology of the lungs.
- Surfactant development - allows lung inflation and decreases the work of breathing and also related to immunology of the lungs.
- Musculoskeletal development - contributes the mechanical elements of ribs, intercostals and diaphragm required for breathing.
Lung Development Stages
The sequence is most important rather than the actual timing, which is variable both in development and in the existing literature.
Lung Stage | Human | Features | Vascular | |
---|---|---|---|---|
Embryonic | week 4 to 5 | lung buds originate as an outgrowth from the ventral wall of the foregut where lobar division occurs | extra pulmonary artery then lobular artery | |
Pseudoglandular | week 5 to 17 | conducting epithelial tubes surrounded by thick mesenchyme are formed, extensive airway branching | Pre-acinar arteries | |
Canalicular | week 16 to 25 | bronchioles are produced, increasing number of capillaries in close contact with cuboidal epithelium and the beginning of alveolar epithelium development | Intra-acinar arteries | |
Saccular | week 24 to 40 | alveolar ducts and air sacs are developed | alveolar duct arteries | |
Alveolar | late fetal to 8 years | secondary septation occurs, marked increase of the number and size of capillaries and alveoli | alveolar capillaries | |

- Endoderm - tubular ventral growth from foregut pharynx.
- Mesoderm - mesenchyme of lung buds.
- Intraembryonic coelom - pleural cavities elongated spaces connecting pericardial and peritoneal spaces.
- Vascular - extra pulmonary artery then lobular artery.
Pseudoglandular stage
|
Human lung pseudoglandular stage[16] |
Canalicular stage
- week 16 - 24
- canalicular phase of the bronchus can be mixed with the pseudoglandular phase.
- Lung morphology changes dramatically, beginning of alveolar epithelium development.
- differentiation of the pulmonary epithelium results in the formation of the future air-blood tissue barrier.
- Surfactant synthesis.
- future gas exchange regions can be distinguished from the future conducting airways of the lungs.
- Vascular - Intra-acinar arteries, canalization of the lung parenchyma by capillaries begins, increasing number of capillaries in close contact with cuboidal epithelium.
Saccular stage
|
Alveolar sac structure |
Alveolar stage
Premature babies have difficulties associated with insufficient surfactant (end month 6 alveolar cells type 2 appear and begin to secrete surfactant). Lung growth continues postnatally to 20-23 years. |
Respiratory secondary septum[17] |
Surfactant
Pulmonary surfactant or simply surfactant (surface active agent) begins to be produced at the canalicular stage and both production and turnover are key for development. It is a mixture of lipids and proteins secreted by Type 2 alveolar cells between alveolar epithelium that reduces surface tension (detergent) at the air-liquid interface. The function of this secretion is to prevent collapse of the lung at the end of expiration. In humans, these cells and their secretion develop towards the very end of the third trimester, just before birth.
Surfactant is mainly phosphatidylcholine (PC) 80% in turn consisting of which dipalmitoyl-PC, palmitoyl-myristoyl-PC and palmitoyl-palmitoleoyl-PC together 75%, anionic phosphatidylglycerol and cholesterol are about 10% each.[18]
The surfactant proteins (SP) SP-A to -D comprise only about 2-5%. Surfactant protein D (SP-D) a multimeric collectin (collagen-containing C-type lectin) involved in innate immunity (anti-microbial)[19] and expressed in pulmonary and non-pulmonary epithelia.[20] Surfactant protein B (SP-B) and disaturated-phosphatidylcholine have both been shown to be higher in preterms with chorioamnionitis.[21]
Clinically surfactants used for surfactant replacement therapy are animal-derived preparations, commonly bovine (beractant, bovactant, BLES) or less common porcine (butantan, poractant-α and surfacen).[22]
Respiratory Species Comparison
Different species undergo lung development stages over different time courses[24] and some species ( mouse and rat) do not possess any respiratory bronchioles, the acini and the ventilatory units are therefore the same entity.

Birth Changes
At birth the lung epithelium changes from a prenatal secretory to a postnatal absorptive function. Several factors have been identified as influencing this transport change including: epinephrine, oxygen, glucocorticoids, and thyroid hormones (for review see[35])
Upper Respiratory Tract
- part of foregut development
- anatomically the nose, nasal cavity and the pharynx
- the pharynx forms a major arched cavity within the pharyngeal arches

Lung Cardiovascular
Pulmonary Circulation
- pulmonary arteries and veins arise by vasculogenesis[36]
Pulmonary Veins
- vasculogenesis in the mesenchyme surrounding the terminal buds during the pseudoglandular stage.
- vasculogenesis - describes the formation of new blood vessels from pluripotent precursor cells.
- angiogenesis in the canalicular and alveolar stages.
- angiogenesis - describes the formation of new vessels from pre-existing vessels.
See also review[37]
Bronchial Circulation
Bronchial Arteries
- vascularising the walls of the airways and the large pulmonary vessels providing giving oxygen and nutrients.
- extend within the bronchial tree to the periphery of the alveolar ducts.
- not found in the lungs until around 8 weeks of gestation.
- one or two small vessels extend from the dorsal aorta and run into the lung alongside the cartilage plates of the main bronchus.
Bronchial Veins
- small bronchial veins within the airway wall drain into the pulmonary veins.
- large bronchial veins seen close to the hilum and drain into the cardinal veins and the right atrium.

TBX
Mouse respiratory Tbx4 and Tbx5 model[38] | Mouse respiratory development[39]]] |
- Nkx2-1 (Titf1) - ventral wall of the anterior foregut, identifies the future trachea.
SOX
- Sox2 is essential for the initiation of lung development from the endodermal gut tube,
- Sox9 is essential for maintaining the tips and associated branching.
Several different Sox types are required for different stages of respiratory development. Wnt/β-catenin signaling does not regulate Sox9 expression in the lung.[29]
Human and mouse Sox expression[27]
FGF
- Localized Fgf10 expression not required for lung branching but prevents epithelial differentiation[40] "As the lung buds grow out, proximal epithelial cells become further and further displaced from the distal source of Fgf10 and differentiate into bronchial epithelial cells. Interestingly, our data presented here show that once epithelial cells are committed to the Sox2-positive airway epithelial cell fate, Fgf10 prevents ciliated cell differentiation and promotes basal cell differentiation."
- Opposing Fgf and Bmp activities regulate the specification of olfactory sensory and respiratory epithelial cell fates[41] " In this study, we provide evidence that in both chick and mouse, Bmp signals promote respiratory epithelial character, whereas Fgf signals are required for the generation of sensory epithelial cells. Moreover, olfactory placodal cells can switch between sensory and respiratory epithelial cell fates in response to Fgf and Bmp activity, respectively. Our results provide evidence that Fgf activity suppresses and restricts the ability of Bmp signals to induce respiratory cell fate in the nasal epithelium."
BMP
Bone morphogenic protein 4 (Bmp4) acts as in an autocrine signalling mechanism to limit bud outgrowth and is therefore involved in branching.
Nkx2-1
Transcriptional control of lung alveolar type 1 cell development and maintenance by NK homeobox 2-1 PNAS "Gas exchange in the lung relies on passive diffusion of oxygen and carbon dioxide across an extraordinarily thin epithelium that is nearly entirely made of the poorly understood alveolar type 1 (AT1) cell. Our study shows that all AT1 cells express and require NK homeobox 2-1 (Nkx2-1) for their development and maintenance. Nkx2-1 mutant AT1 cells lose their characteristic molecular and cellular features and transform toward a gastrointestinal fate, highlighting remarkable plasticity of an otherwise terminally differentiated cell type. This work establishes NKX2-1 as the first overarching factor in the AT1 cell transcriptional hierarchy and paves the way for unraveling not only the unique biology of AT1 cells but also cell type-specific roles of a lineage transcription factor." See also 2012 review paper Signaling Networks Regulating Development of the Lower Respiratory Tract
The NKX2-1 gene encodes a transcription factor that is expressed during early development of thyroid, lung, and neural (forebrain regions including basal ganglia and hypothalamus). NKX2-1 was originally called thyroid transcription factor-1 (TTF1) due to the fact that it mediated thyroid-specific gene transcription.

Other
- Heparan sulfate in lung morphogenesis[42] "Heparan sulfate (HS) is a structurally complex polysaccharide located on the cell surface and in the extracellular matrix, where it participates in numerous biological processes through interactions with a vast number of regulatory proteins such as growth factors and morphogens. ...he potential contribution of HS to abnormalities of lung development has yet to be explored to any significant extent, which is somewhat surprising given the abnormal lung phenotype exhibited by mutant mice synthesizing abnormal HS."
- Signaling via Alk5 controls the ontogeny of lung Clara cells[43] "Clara cells, together with ciliated and pulmonary neuroendocrine cells, make up the epithelium of the bronchioles along the conducting airways. Clara cells are also known as progenitor or stem cells during lung regeneration after injury. ...Using lung epithelial cells, we show that Alk5-regulated Hes1 expression is stimulated through Pten and the MEK/ERK and PI3K/AKT pathways. Thus, the signaling pathway by which TGFbeta/ALK5 regulates Clara cell differentiation may entail inhibition of Pten expression, which in turn activates ERK and AKT phosphorylation."
- Wt1 and retinoic acid signaling in the subcoelomic mesenchyme control the development of the pleuropericardial membranes and the sinus horns[44] "Pericardium and sinus horn formation are coupled and depend on the expansion and correct temporal release of pleuropericardial membranes from the underlying subcoelomic mesenchyme. Wt1 and downstream Raldh2/retinoic acid signaling are crucial regulators of this process."
