PURPOSE To investigate myofibroblast differentiation and signal transduction induced by TGF-beta family members activin A and bone morphogenetic protein (BMP)-7. METHODS Transcription of activin and receptors (ActR) for activin A and BMP-7 was detected by RT-PCR. Levels of marker proteins for differentiation and phosphorylation of similar to mothers against decapentaplegics (Smads) were quant...
Epithelial stem cells reside in specific niches that regulate their self-renewal and differentiation, and are responsible for the continuous regeneration of tissues such as hair, skin, and gut. Although the regenerative potential of mammalian teeth is limited, mouse incisors grow continuously throughout life and contain stem cells at their proximal ends in the cervical loops. In the labial cerv...
BACKGROUND Egg laying in Magang geese is characterized by extended interruption between clutches and lowing laying rate. Both the ovarian follicular development and ovulation characteristics, and the associated endocrine and molecular regulatory mechanisms involved are poorly understood, but could be important for guiding development of molecule aided selection of egg laying performances in gee...
The expression of mRNA for the activin type II receptors (ActRII and ActRIIB), follistatin, and the inhibin/activin subunits was investigated in the follicles of broiler breeder hens. Total RNA was isolated from individual granulosa and theca layers of the F1 through F5 follicles, a pool of the F6 and F7 follicles, the small yellow follicles, and from the combined granulosa and theca layers of ...
