A short review and evaluation of the various cultivation systems for anchorage- dependent cells is given. From the cultivation systems presently available the micro-carrier culture system might be considered to be the most suitable system for large-s

Our observations of bovine follicles indicated that the original histological classifications of atresia were inaccurate. A detailed histological, ultrastructural and immunohistochemical study of antral follicles from bovine ovaries collected from an

As an endocrine organ, the ovary has some unique characteristics. The formation, the maturation and the regression of the hormone producing cells really determine the timing, the amount and the type of hormone secreted. Here, we focus on the granulos

A lot is known about the control of the development of ovarian follicles by growth factors and hormones, but less is known about the roles of extracellular matrix in the control of follicular growth and development. In this review we focus on the spe

Granulosa cell death is an early feature of atresia; however, there are many apparent contradictions in the literature concerning the mode of granulosa cell death. We have therefore examined this process in bovine healthy and atretic antral follicles

During follicular development the proliferative and differentiated state of the epithelioid granulosa cells changes, and the movement of fluid across the follicular basal lamina enables the formation of an antrum. Type IV collagen is an important com

Classically, primordial follicles have flattened pre-granulosa cells that become cuboidal and divide during follicular activation. This change in shape is thus an index of activation. To examine this and follicular morphology in cattle, ovaries were

The cellular biology and changes in the extracellular matrix of ovarian follicles during their development are reviewed. During growth of the bovine ovarian follicle the follicular basal lamina doubles 19 times in surface area. It changes in composit

The membrana granulosa of the ovarian follicle is termed the ‘follicular epithelium’, yet there have been no studies considering its epithelial nature and how it changes during follicular development. Therefore, these issues were investigated usi
