چکیده
The evidence linking aging and cancer is overwhelming. Findings emerging from the field of regenerative medicine reinforce the notion that aging and cancer are profoundly interrelated in their pathogenetic pathways. We discuss evidence to indicate that age-associated alterations in the tissue microenvironment contribute to the emergence of a neoplastic-prone tissue landscape, which is able to support the selective growth of preneoplastic cell populations. Interestingly, tissue contexts that are able to select for the growth of preneoplastic cells, including the aged liver microenvironment, are also supportive for the clonal expansion of normal, homotypic, transplanted cells. This suggests that the growth of normal and preneoplastic cells is possibly driven by similar mechanisms, implying that strategies based on principles of regenerative medicine might be applicable to modulate neoplastic disease.

متن کاملBiological characteristics of Stem Cells from Human Exfoliated Deciduous Teeth (SHEDs) and its therapeutic applications in regenerative medicine
Stem cells isolated from human exfoliated deciduous teeth (SHEDs) are multipotent mesenchymal stem cells that are isolated from dental pulp tissues. These cells have a high proliferative capacity, multipotential ability, immunomodulatory function, and minimal risk of oncogenesis. Recent studies have shown that SHEDs are a feasible cell source for cell therapy and regenerative medicine.
