It is experimentally confirmed that after injury, the Schwann cells (SCs) migrate from the peripheral nervous system towards the site of injury and participate in axon remyelination [1].

Inhibition of growth of Asian keloid cells with human umbilical cord Whartons jelly stem cell-conditioned medium

Keloids are dermal tumors categorized by a group of unusual fibroblasts with excessive deposition of extracellular matrix components such as collagen, elastin, fibronectin, and proteoglycans. Clinically, keloids are characterized by a painful pruritic raised scar that grows beyond the boundary of the original margin of wounds.

Innovative Biomaterials for Bone Regrowth

Bone pathologies are the main causes of disability. With the increase in life expectancy, it is foreseeable that millions of people in many countries will be affected by diseases affecting the bones. The diseases affecting the bone, both acute, such as fractures, and chronic, i.e., osteoporosis and tumors, require treatments which involve the use of cells, growth factors and bone substitutes, as biomaterials/scaffolds, with biocompatibility, osteoinductive, and osteoconductive properties [1–3].

Lung regeneration using amniotic fluid mesenchymal stem cells

Chronic and acute lung diseases pose an increasing socioeconomic problem [1]. The main cause of perinatal morbidity and mortality is preterm birth. It accounts for >85% of all death and complications of perinatal [2].

Management of retinitis pigmentosa by Whartons jelly derived mesenchymal stem cells preliminary clinical results

The retinal pigment epithelium (RPE) forms the outer blood-retinal barrier between photoreceptor cells and choroidal blood vessels. Photoreceptor cells are vitally and functionally dependent on the RPE.

Matrix Elasticity Affects Integrin Expression in Human Umbilical Cord Derived Mesenchymal Stem Cells

Tissue engineering involves functional biomaterial scaffolds and cells for restoring of damaged or diseased tissue. Human umbilical cord-derived mesenchymal stem cells (hUCMSCs) can differentiate into several lineages, including adipose cells, chondrocytes, osteoblasts, neuronal cells, endothelial cells, cardiomyocytes, hepatocyte-like, and pancreatics beta cells [1-3].

Mesenchymal stem cells for systematic therapy

There is still no precise definition for mesenchymal stem cells (MSCs) despite almost half a century having passed since the first isolation of plastic-adherent non-haematopoietic bone marrow (BM) cells capable of clonal expansion [1, 2]. There is also no consensus on nomenclature, with terms including mesenchymal stem cell, mesenchymal stromal cell and multipotent mesenchymal stromal cell – preferred by the International Society for Cell Therapy (ISCT) – all being known by the abbreviation MSC [3].

Molecular and Functional Verification of Wharton’s Jelly Mesenchymal Stem Cells Pluripotency

In general, the ‘stemness’ of cells can be defined as the most primitive cell state that combines two inseparable properties: the ability of self-renewal and the ability to differentiate. More accurately, stem cells (SCs) can generate daughter cells that are identical to their mother cells (self-renewal), as well as progenitor/precursor cells with more restricted potential (differentiation) [1–4].

Molecular Profiles of Cell-to-Cell Variation in the Regenerative Mesenchymal Stromal Cells

Mesenchymal stromal cells (MSCs) are the most common stem cell therapy in clinical trials [1]. This popularity traces back to the groundbreaking research of Friedenstein et al. who identified colony-forming unit fibroblasts (now known as MSCs) in bone marrow [2].
