Mesenchymal stem cells (MSCs) are somatic cells with a dual capacity for self-renewal and differentiation, and diverse therapeutic applicability, both experimentally and in the clinic. These cells can be isolated from various human tissues that may differ anatomically or developmentally with relative ease. Heterogeneity due to biological origin orin vitromanipulation is, nevertheless, considerable and may equate to differences in qualitative and quantitative characteristics which can prove crucial for successful therapeutic use. With this in mind, in the present study we have evaluated the proliferation kinetics and phenotypic characteristics of MSCs derived from two abundant sources, that is, fetal umbilical cord matrix (Wharton's jelly) and adult adipose tissue (termed WJSC and ADSC, resp.) during prolongedin vitroexpansion, a process necessary for obtaining cell numbers sufficient for clinical application. Our results show that WJSC are derived with relatively high efficiency and bear a substantially increased proliferation capacity whilst largely sustaining the expression of typical immunophenotypic markers, whereas ADSC exhibit a reduced proliferation potential showing typical signs of senescence at an early stage. By combining kinetic with phenotypic data we identify culture thresholds up to which both cell types maintain their stem properties, and we discuss the practical implications of their differences.

Background: The prospect of mesenchymal stem cells (MSCs) as an adult stem cell source for neuronal tissue regeneration via their ability to differentiate into neurons has generated considerable excitement in regenerative cell therapy.Methods: In this study, we isolated ovine Wharton’s jelly derived MSCs and expanded in vitro in adherent culture. After the characterisation of MSCs using specific markers, we analysed the culture morphology of MSCs differentiated into neurons by a two-step chemical-based induction protocols involving a pre-induction step and a direct one step chemical-based induction protocol. Morphological changes after induction were evaluated.Result: In both the methods, after neuronal induction, the cells displayed phenotypic characteristic of neurons and comparatively less cytotoxicity was observed in the direct induction method. This study confirmed the possibility of generating neuron like cells from ovine WJ-MSCs and thereby exploring the potential of MSCs as therapeutic tool for treating neurological disorders in Veterinary Medicine.

Migration Potential

Wharton’s jelly mesenchymal stem cells (WJ-MSCs) are multipotent stem cells that can be used in regenerative medicine. However, to reach the high therapeutic efficacy of WJ-MSCs, it is necessary to obtain a large amount of MSCs, which requires their extensive in vitro culturing. Numerous studies have shown that in vitro expansion of MSCs can lead to changes in cell behavior; cells lose their ability to proliferate, differentiate and migrate. One of the important measures of cells’ migration potential is their elasticity, determined by atomic force microscopy (AFM) and quantified by Young’s modulus. This work describes the elasticity of WJ-MSCs during in vitro cultivation. To identify the properties that enable transmigration, the deformability of WJ-MSCs that were able to migrate across the endothelial monolayer or Matrigel was analyzed by AFM. We showed that WJ-MSCs displayed differences in deformability during in vitro cultivation. This phenomenon seems to be strongly correlated with the organization of F-actin and reflects the changes characteristic for stem cell maturation. Furthermore, the results confirm the relationship between the deformability of WJ-MSCs and their migration potential and suggest the use of Young’s modulus as one of the measures of competency of MSCs with respect to their possible use in therapy.

Abstract Mesenchymal stem cells (MSCs) are a highly promising source of adult stem cells for purposes of cell therapy and tissue repair in the field of regenerative medicine. Although the most studied and accessible source of MSC is the bone marrow, the clinical use of bone marrow-derived MSCs (BMSCs) has presented problems, including pain, morbidity, and low cell number upon harvest. For those reasons, we isolated, cultured, and characterized MSCs from a number of tissues; including wharton’s jelly, cord blood, and adipose tissues that were discarded routinely in the past, and evaluated the usefulness of these MSCs compared to BMSCs. Proliferation ability of Wharton’s jelly-derived MSCs (WJ-MSCs), Cord blood-derived MSCs (CB-MSCs), or adipose tissue-derived MSCs (ASCs) was lost at passage 8–10 (22–27 population doubling), passage 7–10, or passage 7–12 (45–50 population doubling), respectively. WJ-MSCs, CB-MSCs, and ASCs expressed CD73, CD90, and CD105, CD90, CD105, and CD166, and CD44, CD73, CD90, and CD166, respectively, were absent for CD14, CD31, and CD45, and differentiated into osteoblast, adipocyte, and chondrogenic lineages under appropriate culture condition. In this study, like BMSCs, WJ-MSCs, CB-MSCs, and ASCs expressed similar cell surface antigens, were able to differentiate into mesenchymal lineages, and possessed highly proliferation potential. Therefore, MSCs isolated from wharton’s jelly, cord blood, and adipose tissue may become useful alternative sources of MSCs to cell therapy and tissue repair in the field of regenerative medicine.

The present work described a bio-functionalized 3D fibrous construct, as an interactive teno-inductive graft model to study tenogenic potential events of human mesenchymal stem cells collected from Wharton’s Jelly (hWJ-MSCs). The 3D-biomimetic and bioresorbable scaffold was functionalized with nanocarriers for the local controlled delivery of a teno-inductive factor, i.e., the human Growth Differentiation factor 5 (hGDF-5). Significant results in terms of gene expression were obtained. Namely, the up-regulation of Scleraxis (350-fold, p ≤ 0.05), type I Collagen (8-fold), Decorin (2.5-fold), and Tenascin-C (1.3-fold) was detected at day 14; on the other hand, when hGDF-5 was supplemented in the external medium only (in absence of nanocarriers), a limited effect on gene expression was evident. Teno-inductive environment also induced pro-inflammatory, (IL-6 (1.6-fold), TNF (45-fold, p ≤ 0.001), and IL-12A (1.4-fold)), and anti-inflammatory (IL-10 (120-fold) and TGF-β1 (1.8-fold)) cytokine expression upregulation at day 14. The presented 3D construct opens perspectives for the study of drug controlled delivery devices to promote teno-regenerative events.

Induced osteogenesis of mesenchymal stem cells (MSCs) may provide an important tool for bone injures treatment. Human umbilical cord and adipose tissue are routinely discarded as clinical waste and may be used as uncontroversial MSCs sources. It still remains to be verified which source of MSCs is the most suitable for bone regeneration.The aim of this research was to investigate the osteogenic potential of human MSCs derived from adipose tissue (ASCs) and Wharton’s jelly of the human umbilical cord (WJ-MSCs) differentiated under the same conditions.Osteogenic differentiation of MSCs was detected and quantified by ARS staining for calcium deposition and alkaline phosphatase (ALP) activity, osteoprotegerin (OPG), and osteocalcin (OC) secretion measurements. Under osteogenic conditions the measured ALP activity and calcium deposition were significantly higher in ASCs than in WJ-MSCs, while the OPG and OC secretion were higher in WJ-MSCs vs. ASCs. Low concentrations of OPG and high levels of OC in ASCs and WJ-MSCs, prove that these cells reached an advanced stage of the osteogenic differentiation. The levels of OC secreted by ASCs were lower than by WJ-MSCs what indicates that the differentiation process of the ASCs reached the stage when the extracellular matrix is overproduced and the down-regulation of OC begins.Both cell types, ASCs and WJ-MSCs possess potential to differentiate towards the osteogenic lineage. However, the observed differences in the levels of osteogenic markers suggest that ASCs may be better candidates for cell-based osteogenesis than WJ-MSCs.
