Aim: To investigate the effectiveness of rat adipose tissue-derived (rAT) mesenchymal stem cell (MSC) transplantation on the functional restoration and regeneration of spinal cord injury (SCI).
Material And Methods: Six of 48 Wistar albino rats were sacrificed to obtain MSCs, and the remaining rats were divided randomly into six groups. SCI was performed using the clip compression method. The control and transplantation groups were injected with physiological saline and a rAT-MSC suspension at the injury sites, respectively. Each animal was evaluated using the Basso, Beattie and Bresnahan (BBB) rating system and sacrificed at 28 days post-injury period (p.i.). The regeneration process was evaluated based on immunostaining against β3-tubulin, BDNF, CNTF, and CNPase.
Results: rAT-MSC transplantation into the SCI site substantially improved the tissue regeneration and functional recovery (p < 0.05). However, the rAT-MSC transplantation at 9 days p.i. was not more efficient on functional recovery than the transplantation immediately after injury. The expression of β3-tubulin, BDNF and CNTF at the injury site indicated the potential for functional regeneration.
Conclusion: The adaptive nature of rat-MSCs enabled the remodulation and regeneration of the lesion site, decreasing the importance of transplantation time in the treatment of SCI.

Adipose tissue-derived mesenchymal stem cells (ADSCs) are crucially involved in various biological processes because of their self-renewal, multi-differentiation, and immunomodulatory activities. Some ADSC's characteristics have been associated with the basic theory of Chinese medicine (CM), especially the Meridian theory. CM can improve the biological properties of ADSCs to facilitate their use in injury treatment, restore immune homeostasis, and inhibit inflammatory responses.

Autologous adipose tissue grafting (AAG) can provide soft tissue reconstruction in congenital defects, traumatic injuries, cancer care, or cosmetic procedures; over 94,000 AAG procedures are performed in the United States every year. Despite its effectiveness, the efficiency of AAG is limited by unpredictable adipocyte survival, impacting graft volume retention (26-83%). Acellular adipose matrices (AAMs) have emerged as a potential alternative to AAG.

Aims: Diabetes mellitus (DM) induces increased inflammation of atherosclerotic plaques, resulting in elevated plaque instability. Mesenchymal stem cell (MSC) therapy was shown to decrease plaque size and increase stability in non-DM animal models. We now studied the effect of MSC therapy in a streptozotocin-induced hyperglycaemia mouse model using a clinically relevant dose of adipose tissue-derived MSCs (ASCs).

Despite the rising incidence of MASLD, the underlying mechanisms of steatosis and lipotoxicity remain poorly understood. Interestingly, lipid accumulation also occurs during fasting, driven by the mobilization of adipose tissue-derived fatty acids into the liver.
