Isolation and purification of human endometrial stromal and glandular cells using immunomagnetic microspheres.

Abstract

Isolation of pure preparations of the different cell populations of human endometrium is a prerequisite for studies of in-vitro function. Sieving of dispersed endometrial cells, followed by adsorption onto immunomagnetic microspheres coated with antibody to Thy-1 was used to separate glandular and stromal cells. The purity of these cell populations was checked with antibodies to cytokeratin and Thy-1. The stromal cells were 98% pure and 90% viable, gland cells were 82% pure with 76% viability. The purified cells were able to proliferate in vitro as shown by thymidine incorporation.
