|
• myogenic differentiation is impaired in vitro and during regeneration even in the presence of exogenous Wnt3a
|
|
• after injury
|
|
• skeletal muscle regeneration is impaired 4 and 6 days after injury with reduced average fiber size and number of regenerating fibers per field of injury and increased apoptosis compared to in similarly treated wild-type mice
• myogenic differentiation during regeneration is inhibited even in the presence of exogenous Wnt3a
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
| N |
• 90% of pups are viable with a normal life span and normal musculature
|
|
• occasionally
|
|
• reduced costochondral and costosternal regions of ribs
• newborns with normal rib cages but occasional anomalies
• floating ribs occasionally misshapen
• occasional osseous knob-like protrusions
|
|
• occasional fusion of cartillagenous portions of ribs
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• 8% to 10% of mice are born small and perform poorly
|
|
• mice are normal at birth but gradually develop weakness and reduced vitality leasing to their death
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• about 8% of mice die by 2 months of age
|
|
• at 3 to 5 months, 18 of 18 surviving mice developed multiple tumors (3 to 5 per mouse) compared to over 100 control mice who did not develop tumors at more than 1 year of age
• however, mice that died prior to 2 months of age did not have tumors and did not die from tumor-related causes
• most tumors are located within the skeletal muscle in the limbs and intercostals regions with some non-skeletal muscle tissues (such as the cerebellum) harboring tumors
• tumors are vascularized, hemorrhagic and cystic spaces are detected in large tumors
|
|
• synovial sarcomas are detected with monophasic (13) outnumbering biphasic (3)
• myxoid and fibrous changes are observed
|
|
• about 8% of mice are born small

• myxoid and fibrous changes are observed
|
|
• myf5+ lineage cells undergo increased apoptosis ate E11.5 and by E15.5 are absent
• however, myf5+ cells near future rib cartilage and skeletal musculogenesis are normal
|
|
• about 8% of mice are born small
