Abstract
Aim: This study investigated the effect of allografting umbilical cord blood mononuclear cells (UCBMCs) into the scrotum on sexual function in male elderly mice. Methods: UCBMCs were injected once into the scrotal sheath cavity of elderly mice. Results: The transplanted UCBMCs survived in the scrotal sheath cavity for 1 month. The mice had significantly increased blood testosterone concentrations, cyclic guanosine monophosphate (cGMP) levels and total nitric oxide synthase (T-NOS) activity in the corpus cavernosum and an increase in the number of mouse matings within 30 min (all p = 0.000). Conclusion: Scrotum-implanted UCBMCs improve the sexual function of male elderly mice through testosterone production and the NOS/cGMP pathway, which may provide an innovative transplantation approach for the treatment of erectile dysfunction.

Abstract
Radiation enteritis is the most common and serious complication of abdominal or
pelvic radiation therapy. Mesenchymal stem cells (MSCs), as well as cell
protection agents, inhibit apoptosis and promote the proliferation of injured
tissues. 3 human umbilical cords MSCs (UCMSCs) were injected into the tail vein
or peritoneal cavity of a rat model of radiation enteritis. The temporary
protective effect was assessed by identification of donor cells, detection of
cellular immune parameters and inflammatory cytokine levels, quantitation of
jejunum mucosal preservation and examination of the rat remaining life. Only the
rats in the intraperitoneal injection group exhibited a few positive donor cells
7 days after transplantation. CD4+/CD8+ T cells, a cellular immune parameter, decreased in the abdominal
exudate of intraperitoneal injection group, compared with the model-only control
and tail vein groups (both P < .05). Both serum and
abdominal exudate TNF-α and IL-6 levels in the intraperitoneally injected rats
rapidly decreased and were significantly different from those in the model-only
control and tail vein injection groups (all P < .05).
Mucosal surface area and survival time increased in the intraperitoneal
injection group compared with the vehicle and tail vein injection groups (all
P = .000). Therefore, the administration of UCMSCs with
intraperitoneal injection approach postponed death in a rat model of radiation
enteritis, which was associated with reduced serum levels of proinflammatory
cytokines (TNF-α, IL-6). However, UCMSCs injected via the tail vein triggered an
intense cellular immune response in the serum that adversely affects their
survival. This treatment failed to suppress circulating serum and abdominal
exudate levels of TNF-α and IL-6 and could not provide a therapeutic benefit for
prolonging life against acute radiation enteritis.
