General Description of OCT-4 .
OCT-4 (also known as POU5F1) is a transcription factor that has been recognized as fundamental in the maintenance of pluripotency in embryonic stem cells and primordial germ cells. It has been proposed as a useful marker for germ cell tumors (GCT) that exhibit features of pluripotentiality (seminoma/dysgerminoma, germinoma and embryonal carcinoma. OCT-4 immunostaining has been shown to be sensitive and specific for GCT, whether in primary gonadal or extragonadal sites or in metastatic lesions.

4-Oct Information for Pathologists


OCT-4 (also Octamer-binding transcription factor 4) is an 18 kDa transription factor encoded by POU5F1. It is considered the master gene in pluripotency and embryonic stem cell regulation. It regulates self-renewal and differentiation of embryonic stem cells, include germ cells.

Common Uses By Pathologists:

OCT-4 is a Nuclear stain. It is highly sensitive and specific for primary intracranial germinomas which may be benign or malignant. Positive staining for OCT-4 is generally related to poor prognostis in esophageal squamous cell carcinoma and possibly in non-small cell lung cancer (NSCLC).
