Summary: This study describes for the first time that all normal prostatic epithelial cells (PEC) intensely react with two monoclonal antibodies directed against distinct epitopes of CD38. Direct comparison of prostatic and lymphatic CD38 using Western blotting revealed identical bands at approximately 45 kD, indicating that the molecules recognized were identical. Immunogold electron microscopy demonstrated anti-CD38 reactivity on the cystoplasmic membrane and within the secretory vacuoles. Double labeling with anti-cytokeratin antibodies confirmed that basal and secretory normal PEC intensely react with anti-C…
