Abstract (original English)

For several years, scientists have focused on studying mesenchymal stem cells because of their ability for self-regeneration, their potential for differentiation into multiple lineages (e.g., osteogenic, chondrogenic, and adipogenic cells), and their low immunogenicity and remarkable capacity to modulate the immune system. The importance of these cells ranges from preserving tissue health and repairing injured tissues in their nearby areas, to their use in scientific investigation for the treatment of neurodegenerative, autoimmune, and cardiovascular diseases. Despite the availability of various tissue sources, such as bone marrow and adipose tissue, their collection and handling may not always be easily achievable. However, dental tissues, such as the pulp and periodontal ligament, are relatively accessible supplies that do not require complex or stressful interventions for the patient. Here, we provide a detailed description of each step involved in the isolation and characterization of mesenchymal stem cells from the pulp and periodontal ligament using monoclonal antibodies ensuring a high level of effectiveness. In addition, we also describe a technique to generate the cellular presenescence state. © 2026 The Author(s). Current Protocols published by Wiley Periodicals LLC.
