Isolation method for a stem cell population with neural potential from skin and adipose tissue

Area of Science:

• Regenerative Medicine
• Stem Cell Biology
• Tissue Engineering

Background:

• Adult human stem cells offer potential for personalized, autologous cell-based therapies due to their homing capabilities.
• Various stem and progenitor cell sources exist, including embryonic, fetal, and adult somatic cells from neural, adipose, and mesenchymal tissues.

Purpose of the Study:

• To describe a straightforward protocol for obtaining enriched cultures of adult stem cells from skin and adipose tissue.
• To evaluate the expansion and characteristics of these stem cells organized in neurospheres.

Main Methods:

• Adult stem cells were isolated from skin and adipose tissue of the same donor.
• Cells were amplified under varied conditions, including slide coating, serum presence, and growth factors like EGF and FGF2.
• Neurospheres were expanded and assessed for proliferation and gene expression.

Main Results:

• Skin and adipose-derived neurospheres exhibited comparable size, cell quantity, and gene expression profiles.
• Optimal cell growth occurred without slide coating, in the presence of serum, and with combined EGF and FGF2.
• The protocol successfully yielded multipotent adult precursor cells.

Conclusions:

• A method for isolating and enhancing multipotent adult precursor cells from accessible skin and adipose tissues is presented.
• This autologous adult stem cell population holds potential for cell replacement and therapeutic applications.
• The findings support the use of these stem cells in personalized regenerative medicine strategies.
