Locomotion of Xenopus epidermis cells in primary culture

Optimized primary culture and subculture of granulosa cells

Background: Primordial follicle includes an oocyte surrounded by a layer of somatic cells called granulosa cells (GCs). GCs, also known as nurse cells, are an important protective element for the growth and survival of oocytes. Oocytes, which lack some of the metabolic processes required granulosa cells for their development. Objective: This manuscript has been provided to explain the protocol...

Primary culture of ovarian follicular cells of Sterlet, Acipenser ruthenus to develop an in vitro system

The aim of the present study was to develop an in vitro system for functional investigation of ovarian follicular cells in Sterlet, Acipenser ruthenus. Oocytes for the primary culture were obtained from the ovaries of a 6 years old Sterlet 729 g in weight and 47 cm in total length. The oocytes were in advanced vitellogenesis stage (PI >10). A part of the ovary (containing about 300 follicles) w...

Studies on the immunogenic properties of La Sota NDV propagated in embryo lung primary cells culture

Morphology and locomotion of individual epithelial cells in culture.

The behaviour in culture of epithelial cells derived from chick embryo pigmented retina epithelium (PRE), corneal epithelium (CE) and epidermis has been studied using time-lapse cinemicrography. The analysis concentrated on the morphology and movement of individual isolated cells, lacking contacts with other cells, during a 24h period starting 1-3 h after the cells were plated out in primary cu...

stem cells of epidermis: a critical introduction

stem cells are the cells having some distinguishing characteristics like longevity, high capacity of self-renewal and differentiation, quiescence and highly error-free proliferation. almost all stem cells have the potential of lineage reprogramming, i.e. inter-conversion of cell lineages. they also have the potential to differentiate into almost all kinds of cells. these cells have been found i...
