CD31 defines a subpopulation of human adipose-derived regenerative cells with potent angiogenic effects.

Cellular heterogeneity represents a major challenge for regenerative treatment using freshly isolated Adipose Derived Regenerative Cells (ADRCs). Emerging data suggest superior efficacy of ADRCs as compared to the ex vivo expanded and more homogeneous ADRCs (= ASCs) for indications involving (micro)vascular deficiency, however, it remains unknown which ADRC cell subtypes account for the improvement. Surprisingly, we found regarding erectile dysfunction (ED) that the number of injected CD31+  ADRCs correlated positively with erectile function 12 months after one bolus of autologous ADRCs.

[Benign scrotal diseases].

Scrotal diseases can be categorised in different ways: Are the patients young or old, or is the condition acute or chronic? Few organs are as easily accessible as scrotum. Nevertheless, it can be difficult to make a correct diagnosis especially in chronic patients. This review divides scrotal diseases in two groups: acute and non-acute diseases.
