Activation of renal vascular smooth muscle TRPV4 channels by 5-hydroxytryptamine impairs kidney function in neonatal pigs.

Control of microvascular reactivity by 5-hydroxytryptamine (5-HT; serotonin) is complex and may depend on vascular bed type and 5-HT receptors. 5-HT receptors consist of seven families (5-HT-5-HT), with 5-HT predominantly mediating renal vasoconstriction. Cyclooxygenase (COX) and smooth muscle intracellular Ca levels ([Ca]) have been implicated in 5-HT-induced vascular reactivity.

Advances and prospects of platelet-rich plasma therapy in veterinary ophthalmology.

In the recent decades, there has been a significant uptick on the use of platelet-rich plasma (PRP) as a better alternative for ophthalmologic therapies in pathologies, primarily of the ocular surface. PRP is a class of liquid platelet concentrate containing a supra-physiological concentration of platelets in a relatively small amount of plasma. Its potential to heal various tissues has piqued interest in its therapeutic application as a biomaterial in regenerative medicine.

Cell-free therapy for canine osteoarthritis: current evidence and prospects.

Osteoarthritis is a progressive degenerative disease affecting joints. It is associated with structural and functional changes that cause lameness and pain in dogs. Mesenchymal stem cells (MSCs) are considered an ideal therapeutic candidate for treating inflammatory musculoskeletal conditions due to their paracrine and immunomodulatory characteristics.

Induction of reactive oxygen species by mechanical stretch drives endothelin production in neonatal pig renal epithelial cells.

Vasoactive endothelin (ET) is generated by ET converting enzyme (ECE)-induced proteolytic processing of pro-molecule big ET to biologically active peptides. HO has been shown to increase the expression of ECE1 via transactivation of its promoter. The present study demonstrates that HO triggered ECE1-dependent ET1-3 production in neonatal pig proximal tubule (PT) epithelial cells.

The preclinical and clinical implications of fetal adnexa derived mesenchymal stromal cells in wound healing therapy.

Mesenchymal stromal cells (MSCs) isolated from fetal adnexa namely amniotic membrane/epithelium, amniotic fluid and umbilical cord have hogged the limelight in recent times, as a proposed alternative to MSCs from conventional sources. These cells which are identified as being in a developmentally primitive state have many advantages, the most important being the non-invasive nature of their isolation procedures, absence of ethical concerns, proliferation potential, differentiation abilities and low immunogenicity. In the present review, we are focusing on the potential preclinical and clinical applications of different cell types of fetal adnexa, in wound healing therapy.
