Introduction,ed, descriptive studies of embryo development have been around for millennia. Aristotle (384–322 BC) wrote a very detailed description of mammalian embryogenesis, similar to the picture we accept today, inferring that the process was driven by an ., known as a “vital force” in later centuries.

The mesenchymal-epithelial interactions in prostate development and the role of testosterone as an inducer of prostate morphogenesis have certainly been a subject of enduring interest, but the lack of molecular markers for prostate di
