Prostate Tumor Cells

These are three of the most widely used prostate cancer models, each representing a distinct disease stage. LNCaP is androgen-sensitive, expresses the androgen receptor (AR), and is derived from a lymph node metastasis. PC-3 and DU 145 are both androgen-independent, castration-resistant lines. PC-3 is highly metastatic and derived from a bone metastasis, while DU 145 comes from a brain metastasis and is often used to study advanced, treatment-resistant disease.

For AR-focused studies, LNCaP and its derivatives (like C4-2, which models progression to castration resistance) are primary choices as they express functional AR. For studying AR-negative or androgen-independent pathways, PC-3 or DU 145 are more appropriate. The key is matching the model's AR status (wild-type, mutant, or null) to your specific research question on hormone signaling or resistance.

Yes, many prostate cancer cell lines, particularly LNCaP and its more advanced derivatives, can be cultured in 3D to form spheroids or used to generate organoids. These models are valuable for studying tumor morphology, drug penetration, and mimicking the in vivo microenvironment more accurately than 2D monolayers.

All cell lines undergo STR (Short Tandem Repeat) profiling to confirm their unique genetic identity and rule out cross-contamination. They are also routinely screened and certified to be free of mycoplasma and other common contaminants to ensure experimental integrity and reproducibility.

Standard protocols are provided with each cell line. Most prostate cancer lines are cultured in RPMI-1640 or DMEM supplemented with 10% FBS. For androgen-sensitive lines like LNCaP, charcoal-stripped serum is often used in experiments to study androgen regulation. Specific recommendations are included in the product documentation.
