Stem cell and regenerative medicine: therapeutic approaches and challenges – a review

Aim: To emphasize the recent updates on stem cell and regenerative medicine - therapeutic approaches and challenges. Objective: To study and review the various available literatures on stem cell and regenerative medicine both their therapeutic approaches and challenges in the field of medicine and dentistry Background: Stem cells have been defined as clone cells that undergo both self-renewal and differentiation to more committed progenitors and functionally specialized mature cells. In the recent times, stem cells have been identified in a variety of tissues of an adult body. Depending on the source, they have the ability to form one or more, or even all cell types of an organism. Stem cell research has shed light on our understanding of developmental biology and offered much hope for cell replacement therapies overcoming a variety of diseases. Reason: The literature survey inoculates the various approaches for the application of stem cell in modern world for the benefit of mankind.
