Isolation and Expansion of Mesenchymal Stem Cells from Human Conjunctival Tissue

Current Protocols in Stem Cell Biology
Samad Nadri, Shahin Yazdani

Abstract

Here we describe a simple protocol for the isolation and culture of mesenchymal stem cells (MSCs) from conjunctiva stromal tissue, with applications to stem cell biology and regenerative medicine. This protocol is based on an explant culture protocol for the adhesion and migration of MSCs from tissue biopsy in primary culture and expansion of the MSC population by passaging cells on the surface of plastic culture dishes. Conjunctiva mesenchymal stem cells (CJMSCs) are generally isolated from small biopsies of human conjunctival tissue. Epithelial sheets are carefully loosened and removed by enzyme treatment after 18 hr and placed in fresh medium supplemented with growth factors. When the cells migrating from tissue segments in primary cultures become nearly confluent, the culture is treated with trypsin. A purified population of CJMSCs that retain proliferation and differentiation potential for many passages can be obtained 2 weeks after the initiation of culture.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.
