Neuronal and cardiac toxicity of pharmacological compounds identified through transcriptomic analysis of human pluripotent stem cell-derived embryoid bodies.

Concurrent with the '3R' principle, the embryonic stem cell test (EST) using mouse embryonic stem cells, developed in 2000, remains the solely accepted in vitro method for embryotoxicity testing. However, the scope and implementation of EST for embryotoxicity screening, compliant with regulatory requirements, are limited. This is due to its technical complexity, long testing period, labor-intensive methodology, and limited endpoint data, leading to misclassification of embryotoxic potential.

Derivation of Induced Pluripotent Stem Cell (iPSC) Lines from Patient-Specific Peripheral Blood Mononuclear Cells (PBMC) Using Episomal Vectors.

Inherited retinal diseases (IRDs) are a diverse group of rare eye disorders, resulting in vision loss or blindness. The underlying reason is mutation in one or more than 250 different genes associated with the development and normal physiology of retina largely comprising of rod/cone photoreceptors and retinal pigment epithelium. Interestingly, the sub retinal region of an eye has been shown to be immune privileged, broadening the scope of cell-replacement therapies for patients suffering from retinal degeneration.

Secretome studies of mesenchymal stromal cells (MSCs) isolated from three tissue sources reveal subtle differences in potency.

Human mesenchymal stromal cells (MSCs) are currently the leading candidate for cell-based therapeutics. While the use of MSCs in transplantation therapies is widely expanding, still, there is a lot of scope for better understanding of the mechanisms underlying their effects. We have generated MSCs from pre- and post-natal human tissue sources such as Wharton's jelly (WJ), stem cells from human exfoliated deciduous teeth (SHED), and bone marrow (BM).

Derivation of three induced pluripotent stem cell lines under feeder-free culture conditions from peripheral blood mononuclear cells (PBMC) of Indian patients suffering from inherited retinal diseases carrying different mutations.

Inherited retinal diseases (IRDs) are clinically and genetically heterogenous diseases affecting the neural retina and retinal pigment epithelium resulting in irreversible blindness. Owing to advantages like ease of access for treatment, one eye being a perfect natural control for the other, and immune privileged environment, research exploring treatment for these retinal diseases has advanced remarkably. We describe the generation of induced pluripotent stem cell (iPSC) lines from peripheral blood mononuclear cells (PBMC) of three patients with IRDs.

The current landscape of the mesenchymal stromal cell secretome: A new paradigm for cell-free regeneration.

The unique properties of mesenchymal stromal/stem cells (MSCs) to self-renew and their multipotentiality have rendered them attractive to researchers and clinicians. In addition to the differentiation potential, the broad repertoire of secreted trophic factors (cytokines) exhibiting diverse functions such as immunomodulation, anti-inflammatory activity, angiogenesis and anti-apoptotic, commonly referred to as the MSC secretome, has gained immense attention in the past few years. There is enough evidence to show that the one important pathway by which MSCs participate in tissue repair and regeneration is through its secretome.

Sequential cultivation of human epidermal keratinocytes and dermal mesenchymal like stromal cells in vitro.

Human skin has continuous self-renewal potential throughout adult life and serves as first line of defence. Its cellular components such as human epidermal keratinocytes (HEKs) and dermal mesenchymal stromal cells (DMSCs) are valuable resources for wound healing applications and cell based therapies. Here we show a simple, scalable and cost-effective method for sequential isolation and propagation of HEKs and DMSCs under defined culture conditions.
