Article Abstract
Adipose stem and progenitor cells (ASPCs) have been isolated from humans and animals for use in regenerative medicine and therapy. However, knowledge of ASPCs in other species is limited. Particularly, ASPCs in livestock are expected to enhance the fat content and meat composition. In this study, we isolated bovine ASPCs using cell surface markers. Specifically, we focused on ASPC markers in humans and experimental animals, namely CD26, CD146, and CD54. Stromal vascular fraction cells from bovine fat were separated using flow cytometry before primary culture. We evaluated the self-renewal and adipogenic potential of each fraction. We identified four cell populations: CD26-CD146+CD54+, CD26-CD146+CD54-, CD26-CD146-, and CD26+CD146-. Among them, the CD26-CD146+ fraction, particularly CD54+, demonstrated the properties of preadipocytes (PreAs), characterized by slow proliferation and a high adipogenic capacity. In conclusion, we could collect and characterize possible PreAs as CD26-CD146+CD54+ or CD26-CD146+CD54-, which are expected for in vitro bovine adipogenic assays in the future.

Background: Several studies have suggested that adult human dermal fibroblasts (HDFa) may be a potential alternative source to mesenchymal stem cells for cell therapies. This study aims to characterize HDFa, adipose-derived stem cells (ADMSCs) and dental pulp stem cells (DPSCs) to investigate their proliferation, differentiation potential, mitochondrial respiration, and metabolomic profile. We identified molecules and characteristics that would differentiate MSCs from different sources or confirm their uniformity.

Limited vascularization and ischemia are major contributors to the chronicity of wounds, such as ulcers and traumatic injuries, which impose significant medical, social, and economic burdens. These challenges are particularly pronounced in patients with spinal cord injury (SCI), a disabling condition associated with vascular dysfunction, infections, and impaired peripheral circulation, complicating the treatment of pressure injuries (PIs) and the success of reconstructive procedures like grafts and flaps. Regenerative medicine aims to address these issues by identifying effective cellular therapies to restore vascular beds.

Regenerative cardiology has emerged as a novel strategy to improve cardiac healing following ischemic injury. While stem-cell-mediated cardiac regeneration has garnered much attention as a promising strategy, its value remains debated owing to the lack of ideal stem cell source candidates. Resident/endogenous cardiac-derived stromal cells (CSCs) exhibit superior therapeutic potential due to their innate abilities to differentiate into cardiac cells, especially cardiomyocytes (CM).

The stress urinary incontinence (SUI) is a difficulty in urology and current sub-urethral sling treatments are associated with inflamation and recurrence. In this study, we developed a novel tissue-engineered sling with myogenic induced adiposederived stem cells (MI-ADSCs) sheets induced by 5-Aza and combined with electrospun scaffolds of silk fibroin and poly(lactide-co-glycolide) (SF/PLGA) for the treatment of stress urinary incontinence. MI-ADSCs increased α-SMA, MyoD and Desmin the mRNA and protein expression.
