background: since embryonic stem (es) cells have the dual ability to proliferate indefinitely and differentiate into multiple tissue types, es cells could potentially provide an unlimited cell supply for human transplantation. objective: in order to study the differentiation of mouse embryonic stem (mes) cells, they were cultured in suspension by using es media without leukemia inhibitory facto...

A 3 × 3 factorial experiment with three levels of fennel extract (FE) (0, 50, and 100 mg/kg of diet) and three levels of added vitamin D3 (Vit D3) (0, 3500 and 4200 IU/kg of diet), was carried out to evaluate reproductive performanceand immune response of post molted broiler breeders(76-84 weeks).Broiler breeders were weighed at 10 week after molting (74 weeks) then randomly distributed into 36...

Early embryonic mortality can be monitored using various techniques and probably the most accurate one is ultrasonography (USG). Since the widespread implementation of transrectal USG for reproductive research in cattle (Griffin and Ginther, 1992), several studies have reported rates of embryonic mortality during early gestation under field conditions. Vasconcelos et al. (1997) characterized em...

Objective: The depletion of platelets in patients under different clinical conditions like thrombocytopenia is often associated with a significant mortality factor. Alternative modes platelet propagation from other resources, including stem cells, are evaluated vitro conditions. Embryonic (ES) cells can proliferate and differentiate into various cell types. This study the generation functional ...

A study to investigate the factors affecting hatchability of Archachatina marginata eggs, had 600 eggs collected from snail pens and incubated in treated substrates; moist soil/sawdust mixture (MSD), sawdust (MD), soil (MSb), dry (DD) (DS) as well rearing (1 m × 1 0.8 m) containing (MSp). Results showed that egg weights  at  laying  ranged  from  250  to&nbsp...
