Kangaroo Mother Care

(KMC) or Kangaroo care (KC) began in Bogota (Colombia) in 1978. It is therapeutic skin-to-skin contact between an infant and parent where the infant is usually held chest-to-chest in an upright prone position. A Cochrane Database review concluded: "Although KMC appears to reduce severe infant morbidity without any serious deleterious effect reported, there is still insufficient evidence to recommend its routine use in LBW infants. Well designed randomized controlled trials of this intervention are needed." PMID 12804436.

karyoplast

(Greek, karyon = kernel or nucleus) Stem cell term describing a nucleus isolated from a eukaryotic cell surrounded by a very thin layer of cytoplasm and a plasma membrane.
(More? Stem Cells)

karyotype

(Greek, karyon = kernel or nucleus + typos = stamp) Term used to describe the chromosomal (genetic) makeup (complement) of a cell by the number and appearance of chromosomes. Note that chromosomes can only be seen in mitosis or meiosis at metaphase.

keratin

(cytokeratin) An intermediate filament protein of the cell cytoskeleton. There are many different keratins with different tissue expression profiles. The most common is often identified in skin and mutations in this gene lead to skin defects.

kidney

A paired excretory organs that filter the blood and also have endocrine functions. The functional unit of the kidney is the nephron and the term renal also applies to the kidney. In humans, embryonically the intermediate mesoderm differentiates to form a series of developmental structures (pronephros, mesonephros) eventually forming the metanephros, that forms the adult kidney.

kinase

See protein kinase.

ketosteroids

A 17-ketosteroid is the excreted inactive derivative (breakdown product) of testosterone formed by conjugation in the liver.

knock out mice

A term used to describe the molecular biology technique of introducing a germ line gene specific disruption that results in mice that do not produce the protein product of that gene, it has been "knocked out". Technique required the development of stem cells to carry out the manipulation.

koilocytes

An epithelial cell visibly infected by human papillomavirus (HPV).

Kolliker's organ

(Kollicker's organ, greater epithelial ridge) A developing cochlear structure consisting of columnar-shaped supporting cells filling the inner sulcus and lying directly under the tectorial membrane. This transient organ regresses and generates the space of the inner sulcus. Named after Rudolph Albert von Kolliker (1817-1905).

Krüppel-like factor

(Klf) Group of evolutionarily conserved zinc finger-containing transcription factors described as having in many different cellular processes:proliferation, apoptosis, differentiation and development.
