Overview
Human benign prostatic hyperplasia (BPH) cells are derived from prostate tissues of patients diagnosed with non-cancerous prostate enlargement. These cells serve as critical tools for understanding the pathophysiology of BPH, which affects aging males through glandular overgrowth and urinary obstruction. BPH cells are available as primary cultures (directly from patient samples) or immortalized lines (genetically modified for prolonged proliferation). Researchers utilize them to investigate androgen signaling, stromal-epithelial interactions, and responses to alpha-blockers or 5-alpha-reductase inhibitors, common BPH therapies.
Key Features
BPH cells exhibit hallmark features of the disease, including upregulated expression of androgen receptors (AR) and prostate-specific antigen (PSA). They often show increased sensitivity to dihydrotestosterone (DHT), a hormone linked to prostate growth. Immortalized BPH cell lines, such as BPH-1, are engineered to bypass senescence but may lose some primary-tissue characteristics. Primary cells, while more physiologically relevant, have limited lifespans and require optimized culture media supplemented with growth factors like epidermal growth factor (EGF).
Application Areas
In pharmaceutical R&D, BPH cells are used to screen drug candidates targeting hormonal pathways or smooth muscle contraction. For example, they help evaluate the efficacy of alpha-1-adrenergic antagonists (e.g., tamsulosin) in reducing prostate stiffness. Academic research employs these cells to study molecular drivers of hyperplasia, such as TGF-β signaling or inflammatory cytokines. Co-culture systems with bladder or urethral cells further model urinary obstruction complications in vitro.
Precautions
Handling BPH cells demands strict aseptic techniques to avoid contamination. Primary cells are particularly sensitive and should be used within early passages (P3–P5) to maintain phenotype stability. Ethical considerations apply for cells sourced from patient tissues, requiring documented informed consent and institutional review board (IRB) approval. Researchers should also validate cell identity via STR profiling and confirm absence of mycoplasma contamination.
B2B Procurement Guide
When sourcing BPH cells, prioritize suppliers providing detailed characterization data (e.g., viability >80%, marker expression profiles). Reputable vendors include ATCC, Lonza, and specialized urology biobanks. For bulk orders, inquire about batch-to-batch consistency and donor demographics (e.g., age, treatment-naïve vs. post-therapy samples). Negotiate storage and shipping terms—lyophilized cells cost less but may reduce viability compared to cryopreserved aliquots.
