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. 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.

Carnegie Stages Comparison
The table below gives an approximate comparison of human, mouse and rat embryos based upon Carnegie staging.
- Note that these Carnegie stages are only approximate day timings for average of embryos.
- Links: Carnegie Stage Comparison
- placenta originates from the ectoplacental cone and the extra-embryonic ectoderm.
- endothelial cells derive from the allantois.
- embryonic day (E 10) - placenta divided into three layers associated with maternal decidual cells.
- Labyrinth - (equivalent to human villi) a selective barrier on the fetal side, is an array of fetal and maternal vessels.
- Junctional zone - (spongy layer) produce hormones and contains numerous cavities. The trophoblast cells form spongiotrophoblasts and the glycogen cells, that later (E 12.5) migrate into the maternal decidua.
- Giant cells - next to the uterine cells form the outermost fetal cell layer until (E 12).

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.

The data below is summarised from a study of early neural development in the mouse.
- 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
A high-resolution description of the developing murine genitourinary tract from Theiler stage (TS) 17 (E10.5) through to TS27 (E19.5) and then to postnatal day 3 was published in 2007.
The GenitoUrinary Development Molecular Anatomy Project (GUDMAP) is a consortium of laboratories working to provide the scientific and medical community with tools to facilitate research. They intend to develop:
- a molecular atlas of gene expression for the developing organs of the GenitoUrinary (GU) tract
- a high resolution molecular anatomy that highlights development of the GU system
- mouse strains to facilitate developmental and functional studies within the GU system
- tutorials describing GU organogenesis
- rapid access to primary data via the GUDMAP database
Vertebrate lung development is generally divided into 5 stages, based upon growth and histological appearance. Mouse age data
|Embryonic||E9 to E11.5||lung buds originate as an outgrowth from the ventral wall of the foregut where lobar division occurs|
|Pseudoglandular||E11.5 to E16.5||conducting epithelial tubes surrounded by thick mesenchyme are formed, extensive airway branching|
|Canalicular||E16.5 to E17.5||bronchioles are produced, increasing number of capillaries in close contact with cuboidal epithelium and the beginning of alveolar epithelium development|
|Saccular||E17.5 to PN5||alveolar ducts and air sacs are developed|
|Alveolar||PN5 to PN28||secondary septation occurs, marked increase of the number and size of capillaries and alveoli|
Human and Mouse Comparison
|Embryonic||week 4 to 5||E9 to E11.5||lung buds originate as an outgrowth from the ventral wall of the foregut where lobar division occurs|
|Pseudoglandular||week 5 to 17||E11.5 to E16.5||conducting epithelial tubes surrounded by thick mesenchyme are formed, extensive airway branching|
|Canalicular||week 16 to 25||E16.5 to E17.5||bronchioles are produced, increasing number of capillaries in close contact with cuboidal epithelium and the beginning of alveolar epithelium development|
|Saccular||week 24 to 40||E17.5 to PN5||alveolar ducts and air sacs are developed|
|Alveolar||late fetal to 8 years||PN5 to PN28||secondary septation occurs, marked increase of the number and size of capillaries and alveoli|
Two postnatal phases identified:
- first phase - (pnd 1 (birth) to pnd 12) corresponds to the hypo-responsive period (SHRP) in the rat. Basal corticosterone levels were low and novelty exposure did not enhance corticosterone or ACTH levels. High expression of CRH in the paraventricular nucleus (PVN) of the hypothalamus. Expression levels of GR in the hippocampus and UCN3 in the perifornical area are low at birth but increase significantly during the SHRP, both reach maximum expression level at pnd 12.
- second phase - mice developed past the SHRP exhibit enhanced corticosterone basal levels and a response of ACTH and corticosterone to mild novelty stress. CRH expression was decreased significantly, expression of urocortin 3 (UCN3) and glucocorticoid receptor (GR) remained high, with a small decrease at pnd 16.
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.

The Genealogy Chart of Inbred Strains
This Nature paper chart shows the origins and relationships of inbred mouse strains. The chart is available as a PDF document [Media:Mouse_genealogy.pdf Locally] or from JAX Labs and was originally published by Beck etal., 2000.
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
