Introduction
The mouse (taxon-mus) has always been a good embryological model, generating easily (litters 8-20) and quickly (21d). Mouse embryology really expanded when molecular biologists used mice for gene knockouts. Suddenly it was necessary to understand development in order to understand the effect of knocking out the gene. There are over 450 different strains of inbred research mice, and these strains have recently been organized into a chart. While being an ideal model organism, only a relatively small amount (1.5%) of the total mouse genome has been sequenced. Those interested in the mouse reproductive cycle should also look at the mouse estrous cycle.
There are several systems for staging mouse development. The original and most widely used is the Theiler Stages system, which divides mouse development into 26 prenatal and 2 postnatal stages. [1]

Carnegie Stages Comparison
The table below gives an approximate comparison of human, mouse and rat embryos based upon Carnegie staging.

Human [6] | Days | 20 | 22 | 24 | 28 | 30 | 33 | 36 | 40 | 42 | 44 | 48 | 52 | 54 | 55 | 58 |

Spermatozoa Development
The process of spermatogenesis takes approximately 35 days:
- mitotic phase (11 days)
- meiotic phase (10 days)
- post-meiotic phase (14 days)
Spermatogonial stem cells (SSCs)
The diploid germ cells, spermatogonial stem cells (SSCs), are located on the basement membrane of the seminiferous tubules
- adult mouse testis about 30,000 SSCs
- either divides into two new single cells
- or into a pair of spermatogonia (Apr)
- that do not complete cytokinesis and stay connected by an intercellular bridge
Primitive spermatogonia subset
- Asingle (As, single isolated spermatogonia)
- Apaired (Apr, interconnected spermatogonial pairs)
- Aaligned (Aal, interconnected 4, 8, or 16 spermatogonia)
- specifically termed Aal-4, Aal-8, and Aal-16
Primitive spermatogonia cells transform without cell division into more differentiating A1 spermatogonia that undergo 6 mitotic and 2 meiotic divisions to eventually form haploid spermatids.
Neural Development
The data below is summarised from a study of early neural development in the mouse.[9]
- initial fusion of apposing neural folds occurred at the level of the intermediate point between the third and fourth somites (caudal myelencephalon) both rostrally and caudally
- second fusion - at the original rostral end of the neural plate (rostrodorsally).
- third fusion - in the caudal diencephalon (rostrally and caudally)
- followed by complete closure of the telencephalic neuropore at the midpoint of the telencephalic roof
- then complete closure of the metencephalic neuropore at the rostral part of the metencephalic roof
- fourth fusion - at the original caudal end of the neural plate (rostrally)
- caudal neuropore completely closed at the level of the future 33rd somite

Mouse Knockouts
Knowledge about mouse development has rapidly expanded as it has become the model animal system for genetic "knock out " studies. This technology actually requires development of defined breeding programs, pseudo-pregnancy, in vitro fertilization, molecular biology, and good old fashioned histology. Without understanding normal development the molecular biologists don't stand a hope of understanding what their gene knock out has done. There is a database of all existing mouse knockouts and their consequences.
Murine Development Control Genes
Kessel, M. and Gruss, P. Science 249 374-379 (1990)
An early review of the genes, and method of identifying them, involved in early mouse development. In particular discusses Homeobox genes. (homeobox is 183bp encoding a 61 amino acid DNA-binding domain)

- Hox
- Pax
- POU
The Genealogy Chart of Inbred Strains
This chart shows the origins and relationships of inbred mouse strains. The chart is available as a PDF document [../pdf/mouse_genealogy.pdf Locally] or from JAX Labs and was originally published by Beck etal., 2000.

Mouse Genome
Mouse Genome completed December 2002, a draft sequence and analysis of the genome of the C57BL/6J mouse strain.
- less than 30,000 genes
- estimated size is 2.5 Gb, smaller than the human genome
- about 40% of the human and mouse genomes can be directly aligned
- about 80% of human genes have one corresponding gene in the mouse genome
