Hand-made cloning (HMC) has proved to be an efficient alternative the conventional micromanipulator-based technique in some domestic animal species. This study reports development of effective culture system for vitro zona-free cloned buffalo (Bubalus bubalis) embryos reconstructed using adult skin fibroblast cells as nucleus donor. Cleavage and blastocyst rates observed were 52 0% modified Charles Rosenkrans 2 (mCR2), 61 4.6% Synthetic Oviductal Fluid (mSOF), 82 40.3% Research Vitro Cleave...

The present study evaluated the effects of glial cell line-derived neurotrophic factor (GDNF), fibroblast growth (FGF) 2 and epidermal (EGF) on proliferation expression some genes in spermatogonial cells. Spermatogonial cells were isolated from prepubertal buffalo testes enriched by double enzyme treatment, filtration through 80- 60-μm nylon mesh filters, differential plating lectin-coated dishes Percoll density gradient centrifugation. Cells then cultured a Sertoli feeder layer formed...

Cumulus cells provide cellular interactions and growth factors required for oogenesis. In vitro studies of oogenesis are limited primarily because the paucity their source, first trimester fetal gonads, small number germ lineage precursor present within these tissues. order to understand this obscure but vitally important process, study was designed direct differentiation embryonic stem (ES) into cells. For purpose, buffalo ES were differentiated, as embryoid bodies (EBs) monolayer adherent...

The 490 and 380 performance records of Karan Fries Swiss cows developed through crossbreeding followed by inter-se mating were evaluated for production, reproduction disposal rate. Duration study (1982-92) was grouped into five periods (1982-83; 1984-85; 1986-87; 1988-89; 1990-92) each year divided four seasons (Winter: Dec.- Jan.; Spring: Feb.-March; Summer: April-June; Rainy: July-Sept.; Autumn: Oct.-Nov). Data also classified according to sire level inbreeding. least squares means FLY...

In this study, we investigated the effect of glial cell line-derived neurotrophic factor (GDNF), fibroblast growth (FGF) 2, and epidermal (EGF) on expression some self-renewal-related microRNAs (miRs) in putative buffalo spermatogonial stem cells (SSCs). The SSCs were cultured a Sertoli feeder layer, colony formation was observed between 7 10 days. SSC colonies expressed markers specific for undifferentiated type A spermatogonia pluripotency markers. After 15 days initial culture,...

In the present study, oocytes retrieved from cross bred Karan Fries cows by ovum pick-up technique were graded into Group 1 and 2, based on morphological appearance of individual cumulus–oocyte complexes (COCs). To analyze whether developmental potential COCs bears a relation to appearance, relative expression panel genes associated with; (a) interaction (Cx43, Cx37, GDF9 BMP15), (b) fertilization (ZP2 ZP3), (c) embryonic development (HSF1, ZAR1 bFGF) (d) apoptosis survival (BAX, BID BCL-XL,...

Spermatogonial stem cells (SSCs) self-renew and produce a large number of differentiated germ to maintain normal spermatogenesis. However, the growth factors crucial for SSC self-renewal mechanism underlying this process remain unclear. In present study, serum-free culture media was used evaluate effect several on expression some markers related genes. The putative SSCs were cultured buffalo Sertoli cell feeder layer in KO-DMEM +10% KOSR. colony formation observed between 7 10 days. colonies...

Buffalo embryos were produced by hand-made cloning using skin fibroblasts from male and female buffaloes (n = 4 each) as donor cells for examining the effect of sex. Although rate blastocyst formation (43.8% ± 1.31% vs. 42.2% 1.22%) was similar, total cell number (333 10.4 270 10.9) higher (p < 0.05) whereas apoptotic index (6.39 0.25 8.52 0.38) lower than blastocysts.
