Stem cells are a promising cell source for regenerative medicine due to their differentiation and self-renewal capacities. In the field of regenerative medicine and tissue engineering, a variety of biomedical technologies have been tested to improve proangiogenic activities of stem cells. However, their therapeutic effect is found to be limited in the clinic because of cell loss, senescence, and insufficient therapeutic activities. To address this type of issue, advanced techniques for biomaterial synthesis and fabrication have been approached to mimic proangiogenic microenvironment and to direct proangiogenic activities. This review highlights the types of polymers and design strategies that have been studied to promote proangiogenic activities of stem cells. In particular, scaffolds, hydrogels, and surface topographies, as well as insight into their underlying mechanisms to improve proangiogenic activities are the focuses. The strategy to promote angiogenic activities of hMSCs by controlling substrate repellency is introduced, and the future direction is proposed.

The heart, with its complex structural and functional characteristics, plays a critical role in sustaining life by pumping blood throughout the entire body to supply nutrients and oxygen. Engineered heart tissues have been introduced to reproduce heart functions to understand the pathophysiological properties of the heart and to test and develop potential therapeutics. Although numerous studies have been conducted in various fields to increase the functionality of heart tissue to be similar to reality, there are still many difficulties in reproducing the blood-pumping function of the heart.

Background: The nod-like receptor family pyrin domain-containing 3 (NLRP3) has been implicated in various skin diseases. However, its role in mediating 2, 4-dinitrofluorobenzene (DNFB)-induced chronic itch remains unclear.
Methods: Widetype () and deletion ( )mice, the expression of transient receptor potential (TRP) ankyrin 1 (TRPA1) inhibitor or recombinant mice interleukin-18 (IL-18) were used to establish and evaluate the severity of DNFB-mediated chronic itch.

Introduction: Chronic inflammation is a major risk factor for coronary artery disease (CAD). Currently, the inflammatory cardiovascular risk is assessed via C-reactive protein (CRP) levels measured using a high-sensitivity assay (hsCRP). Monomeric CRP (mCRP) is a locally produced form of CRP that has emerged as a potential biomarker of inflammation.

Neutrophil elastase () mutations are the most common cause of cyclic (CyN) and congenital neutropenia (SCN), two autosomal dominant disorders causing recurrent infections due to impaired neutrophil production. Granulocyte colony-stimulating factor (G-CSF) corrects neutropenia but has adverse effects, including bone pain and in some cases, an increased risk of myelodysplasia (MDS) and acute myeloid leukemia (AML). Hematopoietic stem cell transplantation is an alternative but is limited by its complications and donor availability.

Stem cell research is a major focus for scientific and medical communities worldwide due to the potential for stem cells to restore function lost due to disease, trauma, congenital abnormalities, and aging. Stem cells can repair, replace, or regenerate damaged cells, tissues, or organs, making them an important area of research in regenerative medicine. India is emerging as a prominent hub for the development of stem cell therapy (SCT), and it is important to assess the current state of stem cell research in India and the potential for advancement to promote stem cell-based therapy.
