Abstract EN
Equine metabolic syndrome (EMS) is mainly characterized by insulin resistance, obesity, and local or systemic inflammation.
That unfriendly environment of adipose tissue has huge impact on stem cells population (ASC) residing within.
In the present study, using molecular biology techniques and multiple imaging techniques (SEM, FIB-SEM, and confocal microscopy), we evaluated the impact of EMS on ASC viability and chondrogenic differentiation.
Moreover, we visualized the mitochondrial network and dynamics in ASCCTRL and ASCEMS during control and chondrogenic conditions.
In control conditions, ASCEMS were characterized by increased mitochondrial fission in comparison to ASCCTRL.
We found that extensive remodeling of mitochondrial network including fusion and fission occurs during early step of differentiation.
Moreover, we observed mitochondria morphology deterioration in ASCEMS.
These conditions seem to cause autophagic shift in ASCEMS, as we observed increased accumulation of LAMP2 and formation of multiple autophagosomes in those cells, some of which contained dysfunctional mitochondria.
“Autophagic” switch may be a rescue mechanism allowing ASCEMS to clear impaired by ROS proteins and mitochondria.
Moreover it provides a precursors-to-macromolecules synthesis, especially during chondrogenesis.
Our data indicates that autophagy in ASCEMS would be crucial for the quality control mechanisms and maintenance of cellular homeostasis ASCEMS allowing them to be in “stemness” status.
