N | normal phenotype |
• mice die within 1 day of birth, from dessication and maternal neglect, secondary to developmental malformations
|
• recto-vaginal septum is absent, resulting in common cloacal opening
|
• from E9-12.5, limb buds are reduced and dysmorphic
|
• AER is absent and limb bud has only a simple, single-layered epithelium at distal tip
|
• at E9-12.5
|
• small, resulting in shortening of tail
|
• mice show dysmorphic craniofacial bone development
|
• mice have small, truncated mandibles compared to wild-type
|
• mice have small, truncated maxilla compared to wild-type
|
• secondary palate is truncated
|
• stratified squamous epithelium is replaced by 1-2 layers of cuboidal epithelial cells
|
• small, resulting in shortening of tail
|
• at E15, homozygotes lack distal components of the forelimb, including the radius, carpals and digits
|
• limb truncations due to failure to maintain the apical ectodermal ridge (AER)
|
• from E9-12.5, limb buds are reduced and dysmorphic
|
• AER is absent and limb bud has only a simple, single-layered epithelium at distal tip

• stratified squamous epithelium is replaced by 1-2 layers of cuboidal epithelial cells
|
• there are abundant ciliated and goblet cells that are not seen in wild-type esophageal epithelium
|
• esophageal lining shows pseudostratified columnar appearance similar to respiratory epithelium
|
• recto-vaginal septum is absent, resulting in common cloacal opening
|
• E18 fetuses exhibit a well-developed columnar epithelium in the proximal stomach rather than a mature squamous epithelium as in wild-type fetuses and exhibit markers of Barrett's esophagus
• E18 fetuses exhibit epithelial metaplasia in the proximal stomach
|
• between E13 and E18, the proximal stomach epithelium undergoes a transition to a Barrett's-like metaplasia
• origin of the metaplasia is traced to a monolayer of Car4+cells that lie on the basement membrane of the proximal stomach and the Car4+ primitive epithelium of the stomach develops into a metaplasia after E14 because of the absence of an undermining population of squamous epithelium from the esophagus
|
• mutants develop Barrett's-like metaplasia; origin of metaplasia is the primitive junctional epithelial cells of the squamocolumnar junction
|
• no prostatic ducts or epithelial budding structures are detected in the ventral or dorsolateral region of the periurethral mesenchyma, unlike in wild-type controls
|
• newborn males show absence of the prostate
|
|
• mutants develop a bladder mucosa epithelial layer but fail to complete uroepithelial differentiation, producing a nontransitional default cuboidal epithelium
• mutants do not form the umbrella cells that make up the apical cell layer of the bladder epithelium
• mutants do not complete uroepithelial differentiation and thus do not develop the transitional epithelium but rather a nontransitional cuboidal epithelium
|
• absent in some regions
|
• thinner than normal
|
• no prostatic ducts or epithelial budding structures are detected in the ventral or dorsolateral region of the periurethral mesenchyma, unlike in wild-type controls
|
• newborn males show absence of the prostate
|
• caudal structures are hypoplastic, with reduction in supporting connective tissue
• stratified squamous epithelium is absent on external genitalia, introitus, and vagina
• uterine Mullerian epithelium is contiguous with vaginal mucosa composed of urogenital and cloacal epithelia
|
• recto-vaginal septum is absent, resulting in common cloacal opening
|
|
• embryos demonstrate clitoral hypoplasia, due to absence of mature erectile tissue and overlying skin
|
• similar transfiguration as in stomach epithelium is observed
|
• similar transfiguration as in stomach epithelium is observed
|
• mutants have no eyelids at P1
|
• in the nasal epithelial at E11.5
|
• cells in remaining patches of epithelium on dermis have highly pyknotic nuclei, indicative of apoptosis
|
• secondary palate is truncated
|
• stratified squamous epithelium is replaced by 1-2 layers of cuboidal epithelial cells
|
• hair shafts are absent at P1
|
• no pelage follicles are present at P1
|
• stratified epidermis is absent, and basal, suprabasal and cornifed layer structures are lacking in mutants; late stage embryos and neonates retain isolated patches of disorganized epithelial cells along exposed dermis

• mutant ciliated cells make contact with the basement membrane, unlike cells in wild-type mice
|
• neonatal tracheobronchial epithelium shows a significantly higher number of ciliated cells than in wild-type controls
