background: the basal medium that supports isolated mouse oviduct (imo) is important for supporting embryo development and quality. methods: the culture of ovine ivm/ivf zygotes was done in imo using sofaacibsa and sofaabsa as basal medium of imo and in sofaabsa alone as control. for preparation of imo mature inbred strain c57bl/6 female mice were synchronized and mated with vasectomized males....

objective: growth differentiation factor 9b (gdf9b) is an oocyte-derived growth factor. this protein is essential for the development of ovarian follicles and acts mainly by binding to its receptor on the surface of granulosa cells. the effect of gdf9b on the growth of follicles in various developmental stages, particularly primordial and primary follicles, is unknown. thus the aim of this stud...

Background  Isolation of adipose tissue mesenchymal stem cells (MSCs) with current enzymatic methods has some limitations. For example, it is costly and time-consuming and results in a heterogeneous cell population that making compromise proliferation and differentiation of MSCs. Also, it is accompanied with the increased risk of culture contaminations because of several handling steps.In this...

The aim of this study was to evaluate the effects of ovarian tissue vitrification and two-step in vitro culture on the metaphase II (MII) oocyte reactive oxygen species (ROS) level, mitochondrial transcription factor A (TFAM) expression and succinate dehydrogenase (SDH) activity. After collection of neonatal mouse ovaries, 45 ovaries were vitrified and the others (n = 45) were...

Proteoglycans (PGs) synthesized by chick corneal stromal cells in cell culture and organ culture were metabolically radiolabelled with [35S]sulfate (for glycosaminoglycans) and [3H]leucine (for core proteins). Media, cell extracts and organ extracts from cultures were chromatographed on DEAE-Sephacel columns and separated into three fractions: the pass-through fraction (Fraction 1: nonsulfated ...
