Tissue culture of normal human post-pubertal prostate

Area of Science:

• Urology
• Cell Biology
• Tissue Engineering

Background:

• Establishing viable primary cell cultures from prostate tissue is crucial for research.
• Previous attempts with diseased prostate tissue have shown limited success in cell culture.

Purpose of the Study:

• To investigate the feasibility of establishing and maintaining primary epithelial cell cultures from healthy young male donor prostates.
• To compare the growth characteristics of healthy prostate epithelial cells with those from benign prostatic hyperplasia and prostatic carcinoma.

Main Methods:

• Prostatectomy specimens from 10 young male cadaver renal donors were used for explant cultures.
• Cells were cultured in Falcon flasks, and growth kinetics (latency, confluence) were monitored.
• Passaging of established monolayers was performed at a specific cell density.
• Comparison of culture outcomes with explants from benign prostatic hyperplasia and prostatic carcinoma tissues.

Main Results:

• Rapid monolayer growth of predominantly epithelial cells from healthy donors with a short latency (3-5 days) and confluence achieved in 15-17 days.
• Established monolayers supported vigorous epithelial cell growth upon passaging.
• Fibroblast overgrowth was observed in long-term cultures of healthy donor cells.
• Explant cultures from benign prostatic hyperplasia and prostatic carcinoma showed longer latency, failed to reach confluence, and could not be passaged.

Conclusions:

• Primary epithelial cell cultures from healthy young male donor prostates can be successfully established and maintained.
• These healthy prostate cells exhibit robust growth and passaging capabilities, distinct from diseased tissues.
• The susceptibility to fibroblast overgrowth presents a challenge for long-term culture of healthy prostate epithelial cells.
