Importantly, vascular senescent cells are identified by key characteristics and biomarkers including cell cycle regulators (i.e., cdkn1a - p21, Cdkn2a - p16 and p19), altered lysosomal activity (senescence-associated -galactosidase [SA--Gal]), DNA damage markers (53BP1 and -H2AX), telomere length and telomerase activity, senescent cell anti-apoptotic pathways (SCAPs), and SASP profile (IL-6, IL-1, and tumor necrosis factor [TNF-], among many others) [31,45] [Figure 1]
These markers are commonly used in experimental bone and connective tissue studies to evaluate vascular activation and endothelial participation in tissue regeneration

Why accurate hCG reconstitution matters for TRT patients In the context of TRT, hCG is used to stimulate endogenous testicular activity by mimicking luteinising hormone (LH)
