Three-dimensional cell culture using CD9-positive cells isolated from marginal cell layer of intermediate lobe of rats sustains in vivo-like primary niche environment
The adenohypophysis is composed of the anterior and intermediate lobes (AL and IL, respectively), and secretes hormones that play an important role in reproduction. CD9- and SOX2-double (CD9/SOX2) positive cells located in the marginal cell layer (MCL) facing the Rathke’s cleft in the AL and IL form the primary stem cell niche in the adult adenohypophysis of rats. In this study, we successfully obtained 3-dimensional (3D) cell aggregates that closely resembled the primary niche of MCL in vivo. After incubation in a Matrigel containing several growth factors, approximately 20% of the cells in the CD9/SOX2-positive cell aggregates were differentiated into hormone-producing cells. The cell aggregates generated in this study may provide insight into the regulation of the pituitary stem/progenitor cell niche and the turnover of hormone-producing cells.
期刊介绍：
Journal of Reproduction and Development (JRD) is the
official journal of the Society for Reproduction and Development,
published bimonthly, and welcomes original articles. JRD
provides free full-text access of all the published articles on
the web. The functions of the journal are managed by Editorial
Board Members, such as the Editor-in-Chief, Co-Editor-inChief, Managing Editors and Editors. All manuscripts are
peer-reviewed critically by two or more reviewers. Acceptance
is based on scientific content and presentation of the materials.
The Editors select reviewers and correspond with authors. Final
decisions about acceptance or rejection of manuscripts are made
by the Editor-in-Chief and Co-Editor-in-Chief.
