Prostate Cancer Organoid Models

Prostate cancer (PCa) is one of the most malignant tumors among men, which presents a high heterogeneity and incidence rate around the world. Relapse and resistance often occur after current treatment and progress to neuroendocrine carcinoma or metastasis to other organs. There is an urgent need to increase the knowledge of pathogenesis and complex heterogeneity to enhance the development of promising drugs and therapies for patients. Cancer organoid is a powerful 3d culture that recapitulates the key features of clinical tumor tissue and allows genetic manipulation to study the mechanism of origin. Moreover, the organoid is a proper model for in vitro large-scale screening and tests.

Prostate Cancer-related CAR-T Products and Services at Creative Biolabs

Creative Biolabs is a leader in CAR-T therapy development. We have extensive CAR-cell therapy-related products and offer customized CAR-T development services for various tumors to clients worldwide.

Target Antigen	Target Description	CAR-T Products
PSCA	PSCA is a prostate cancer-related protein that expresses on the surface of basal and secretory epithelial cells. The protein is also associated with gastric, renal, and pancreatic cancer.	Anti-PSCA CAR-T
EpCAM	Epithelial cell adhesion molecule (EpCAM) mediates cell-cell adhesion in epithelia and is relevant to cell growth and metastasis. EpCAM is a potential target for immunotherapy of various solid tumors.	Anti-EpCAM CAR-T
PSMA	Prostate-specific membrane antigen (PSMA) is mainly expressed on prostate cancer cells and serves as a diagnostic biomarker and targeted protein for clinical treatment.	Anti-PSMA CAR-T
PSA	Prostate-specific antigen (PSA) is widely present in normal and cancer cells of prostate tissues, but the concentration is increased in patients' blood with prostate cancer.	Anti-PSA CAR-T
PAP	Prostatic acid phosphatase (PAP) is the secretory glycoprotein from prostate epithelial cells, and the elevated concentration of PAP in human blood indicates prostate cancer and neoplastic hematologic disorder.	Anti-PAP CAR-T

Creative Biolabs has committed to cancer organoid technology and is continually discovering to simulate the tumor features and microenvironment to more extent. If you have trouble with cancer organoids culture and application, please contact us for help.
