Purification of human induced pluripotent stem cell-derived neural precursors using magnetic activated cell sorting

Nanotechnology at the crossroads of stem cell medicine

Nanotechnology in stem cell medicine is an interdisciplinary field which has gained a lot of interest recently. This domain addresses key challenges associated with stem cell medicine such as cell isolation, targeted delivery, and tracking. Nanotechnology-based approaches, including magnetic cell sorting, fluorescent tagging, and drug or biomolecule conjugation for delivery, have enhanced precision in stem cell isolation and guided cell migration, increasing the therapeutic potential. Recent studies have focused on using nanomaterials and scaffolds to drive stem cell differentiation by activating specific molecular pathways, achieved through embedding biomolecules within the scaffold or through the scaffold's material composition and structure alone. These innovations hold promise in therapeutic applications across various diseases, including cancer stem cell targeting, neurodegenerative disorders, pre-eclampsia, cardiovascular conditions, and organoid development. This review examines recent advancements in the field, explores potential applications like biosensors and nanochips, and highlights the challenges and research gaps.

Nanotechnology shaping stem cell therapy: Recent advances, application, challenges, and future outlook

Currently, stem cell nanotechnology is one of the novel and exciting fields. Certain experimental studies conducted on the interaction of stem cells with nanostructures or nanomaterials have made significant progress. The significance of nanostructures, nanotechnology, and nanomaterials in the development of stem cell-based therapies for degenerative diseases and injuries has been well established. Specifically, the structure and properties of nanomaterials affecting the propagation and differentiation of stem cells have become a new interdisciplinary frontier in material science and regeneration medicines. In the current review, we highlight the recent major progress in this field, explore the application prospects, and discuss the issues, approaches, and challenges, to improve the applications of nanotechnology in the research and development of stem cells.

Neural Stem Cells and Methods for Their Generation From Induced Pluripotent Stem Cells in vitro

Neural stem cells (NSCs) provide promising approaches for investigating embryonic neurogenesis, modeling of the pathogenesis of diseases of the central nervous system, and for designing drug-screening systems. Such cells also have an application in regenerative medicine. The most convenient and acceptable source of NSCs is pluripotent stem cells (embryonic stem cells or induced pluripotent stem cells). However, there are many different protocols for the induction and differentiation of NSCs, and these result in a wide range of neural cell types. This review is intended to summarize the knowledge accumulated, to date, by workers in this field. It should be particularly useful for researchers who are beginning investigations in this area of cell biology.
