title: Influence of a corpus luteum tissue extract on rabbit ovarian mesothelial cells.
abstract: This study investigates rabbit ovarian mesothelial (OM) cells exposed in vitro to a crude corpus luteum extract (CLE; 60 micrograms/ml). The growth of OM cells was evaluated by measuring the change in cell number (mean % +/- standard error of mean, SEM), the number of cell population doublings (CPD +/- SEM), and the cell population doubling time in hours (CPDT +/- SEM) after 7.5 days of culture in a serum-poor medium. Quantitative estimates of surface morphology changes were obtained by analyzing the total number (mean no. +/- SEM), density (mean no./100 microns 2 +/- SEM), and length-to-diameter ratio (mean L/D +/- SEM) of microvilli. OM cells in control medium formed loosely cohesive monolayers, and grew 152.53 +/- 11.01% with a CPD of 0.59 +/- 0.08 and a CPDT of 117.29 +/- 6.43 hours. The exposed surface area of these cells was over 8,000 microns 2 and was covered in its epinuclear region by long and slender microvilli with a L/D of 6.01 +/- 0.29. The total number of microvilli in each control cell was 1977.52 +/- 120.49 with a density of 0.58 +/- 0.03/100 microns 2 in the epinuclear region and of 0.05 +/- 0.003/150 microns 2 in the remaining surface area (5,161.62 +/- 354.43 microns 2). In contrast, CLE-rich cells cultures grew 329.57 +/- 16.65%, with a CPD of 1.71 +/- 0.07 and a CPDT of 53.43 +/- 2.93 hours.(ABSTRACT TRUNCATED AT 250 WORDS)
