1. Cervical Disc Degeneration: نظرة عامة
Cervical disc degeneration is a common age-related condition characterized by the progressive loss of extracellular matrix components and cellularity within the intervertebral discs (IVDs). This leads to a decrease in disc height, increased stiffness, and reduced shock absorption, resulting in pain, صلابة, والعجز العصبي.
2. Stem Cell Biology and Regenerative Potential
Stem cells possess the unique ability to self-renew and differentiate into specialized cell types, making them promising candidates for regenerative therapies. يمكن اشتقاقها من مصادر مختلفة, بما في ذلك الجنينية, بالغ, or induced pluripotent stem cells, each with its own advantages and limitations.
3. Stem Cell Sources for Cervical Disc Regeneration
Various stem cell sources have been explored for cervical disc regeneration, including bone marrow-derived mesenchymal stem cells (اللجان الدائمة), adipose-derived stem cells (ADSCs), والخلايا الجذعية المحفزة (iPSCs). Each source offers specific advantages, such as availability, ease of isolation, and differentiation potential.
4. Preclinical Studies on Stem Cell Therapy
