The growth differentiation factor 9 (GDF9) gene plays a vital role in the and maturation of ovarian follicles laying hens. However, its messenger ribonucleic acid (mRNA) expression levels preovulatory indigenous chickens remain poorly understood. study aimed to identify association between egg weight quality traits, morphology, mRNA GDF9 pre-ovulatory South African Potchefstroom Koekoek chicken...
Retinoic acid (RA) stimulates the clonal proliferation of mature bone marrow progenitor cells and inhibits the growth of leukemic progenitors, whereas its effects on normal primitive hematopoietic progenitors have not yet been investigated. This study investigated the ability of all-trans- and 9-cis-RA to modulate the proliferation and differentiation of murine Lin-Sca-1+ bone marrow progenitor...
CONTEXT Genes from the ovarian bone morphogenetic signaling pathway (GDF9 and BMP15) are critical for normal human fertility. We previously identified a deletion mutation in GDF9 in sisters with spontaneous dizygotic (DZ) twins, but the prevalence of rare GDF9 variants in twinning families is unknown. OBJECTIVE The objective was to evaluate the frequency of rare variants in GDF9 in families w...
Efficient osteogenic differentiation and bone formation from mesenchymal stem cells (MSCs) should have clinical applications in treating nonunion fracture healing. MSCs are adherent bone marrow stromal cells that can self-renew and differentiate into osteogenic, chondrogenic, adipogenic, and myogenic lineages. We have identified bone morphogenetic protein 9 (BMP-9) as one of the most osteogenic...
Growth differentiation factor-9 (GDF9) is an oocyte secreted paracrine factor essential for mammalian ovarian folliculogenesis. Like other members of the transforming growth factor-beta (TGFbeta) superfamily, GDF9 is synthesized as a prepropeptide which needs processing by furin-like proteases to result in an active mature protein. We have previously characterized a preparation of unpurified re...
The oocyte-secreted polypeptide growth factors, growth differentiation factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15, also known as GDF9B) have both been shown to be essential for ovarian follicular growth and function. The effects of murine (m) and ovine (o) GDF9 as well as oBMP15, alone or together, on 3H-thymidine uptake and progesterone and inhibin production by granulosa cells f...
