Suplementação proteica no meio de cultivo in vitro de folículos pré-antrais / Protein supplementation on In Vitro Preantral Follicle Medium Culture

ABSTRACT

The in vitro culture of preantral follicles is an important tool to elucidate the mechanisms involved in controlling early folliculogenesis as well as to improve reproductive efficiency by providing a large number of oocytes for in vitro production of embryos. To this end, improvements in the performance of current culture systems are needed, including changes in the composition of the medium. Supplementation of culture medium with proteins is a great strategy to improve survival and in vitro development of preantral follicles. This review highlights the importance of in vitro culture of preantral follicles with emphasis on the main protein sources used to supplement the culture media.
