Popis: | The present study was designed to investigate whether gonadotropins [follicle-stimulating hormone (FSH) and luteinizing hormone (LH)] and buffalo follicular fluid (bFF) supplementation in maturation medium influences the transcript abundance of germ cell marker genes [maternal antigen that embryos require (MATER), Zygote arrest 1 (ZAR1), growth differentiation factor 9 (GDF9), and bone morphogenetic protein 15 (BMP15)] mRNA in buffalo (Bubalus bubalis) oocytes. Buffalo ovaries were collected from local abattoir, oocytes were aspirated from antral follicles (5–8 mm) and matured in vitro using two different maturation regimens, viz, group A: gonadotropin (FSH and LH) and group B: non-gonadotropin-supplemented maturation medium containing 20% buffalo follicular fluid (bFF). mRNA was isolated from immature (330) and in vitro matured oocytes from both the groups (A, 320; B, 340), and reverse transcribed using Moloney murine leukemia virus reverse transcriptase. Expression levels of MATER, ZAR1, GDF9, and BMP15 mRNA transcripts were analyzed in oocytes of both maturation groups as well as immature oocytes using real-time PCR. QPCR results showed that GDF9 and BMP15 transcripts were significantly (p |
