Uterine secretory activity and histology of prepubertal female dogs in an animal model of partial ablation of endometrial glands development

Pesqui. vet. bras; 40 (2), 2020
Inadequate exposure of the female reproductive system to steroids in uterine developmental periods can partially inhibit the development of endometrial glands in dogs. However, the effects of steroids on the formed glands functionality remain unknown, as well as the possible occurrence of endometrial fib...

Co-transfection of hepatocyte growth factor and truncated TGF-β type II receptor inhibit scar formation

Braz. j. med. biol. res; 53 (1), 2020
Wound scarring remains a major challenge for plastic surgeons. Transforming growth factor (TGF)-β plays a key role in the process of scar formation. Previous studies have demonstrated that truncated TGF-β type II receptor (t-TGF-βRII) is unable to continue signal transduction but is still ...
