We describe the manufacture of compressed hormone pellets, as well as subcutaneous surgical implantation into mice. This strategy can be combined with the growth of cell and tissue xenografts under the renal capsule of athymic nude mice to evaluate hormonal carcinogenesis and regulation of benign prostate growth.

Human pluripotent stem cells (hPSCs) have the potential to treat a myriad of different diseases. The utility of these cells lies in the fact that they can differentiate into any cell type in the body. Here we describe the teratoma assay, which is used to demonstrate the pluripotence of hPSCs.

In this video, we describe the procedure for the dissection of the urogenital system or UGS from a male mouse model. This UGS is further dissected ex vivo to isolate the prostate gland and study its role in prostate cancer development.
FAQs
Its position provides a reference boundary for interpreting the prostate relative to the bladder, rectum, and proximal urethra. This relationship helps clinicians understand where prostatic tissue lies within the pelvis and how the gland is separated from adjacent structures. The capsule therefore serves as an important anatomical landmark during examination, imaging interpretation, and operative planning.
The capsule does not appear equally thick or equally distinct in every region. This regional variation can affect how clearly the boundary is recognized on anatomical assessment or imaging. Clinicians must therefore interpret the capsule together with the surrounding prostate and adjacent structures rather than treating its appearance as uniform throughout the gland.
A tumor confined within the capsule suggests that disease remains bounded by the prostate’s anatomical covering, whereas extension beyond it indicates involvement outside that boundary. This distinction contributes to cancer staging and can influence treatment selection. It also provides context for evaluating whether surgery has achieved clear margins around the removed tissue.
These neighboring structures establish the prostate’s position and help orient anatomical assessment. The bladder lies above, the rectum lies behind, and the proximal urethra passes through the gland region. Recognizing these relationships supports consistent interpretation during digital rectal examination, magnetic resonance imaging, biopsy planning, and surgical procedures involving the prostate.
Because the prostate lies in front of the rectum, the capsule and the gland can be assessed in relation to the rectal surface during a digital examination. This anatomical access helps clinicians evaluate the prostate’s position and palpable features. The examination provides clinical information that may complement imaging or guide decisions about further assessment.
The capsule provides a boundary for locating suspicious prostatic tissue and judging its relationship to the gland’s edge. During biopsy planning, this anatomical reference helps organize sampling considerations. On magnetic resonance imaging, the capsule’s visibility and the position of a suspected lesion can support assessment of whether disease appears confined to the prostate or extends beyond it.
During surgery, the capsule helps define the prostate’s outer anatomical boundary and its relationship to nearby structures. Surgeons can use this information when planning how the gland is approached and removed. In cancer care, examining whether tumor reaches beyond the capsule also contributes to postoperative assessment of disease extent and surgical margins.
