3D cultures have gained attention in the field of regenerative medicine for their usefulness as in vitro model of solid tissues. Bottom-up technology to generate artificial tissues or organs is prospective and an attractive approach that will expand as the field of regenerative medicine becomes more translational. We have characterized c-kit positive cardiac stem cells after long-term cultures ...

Infertility in women is a health priority. Designing a robust culture protocol capable of attaining complete follicle growth is an exciting challenge, for its potential clinical applications, but also as a model to observe and closely study the sequence of molecular events that lie behind the intricate relationship existing between the oocyte and surrounding follicle cells. Here, we describe th...

Introduction: In HIV-associated tuberculosis cases, identifying nontuberculous Mycobacteria (NTM) from clinical samples has become essential regarding patients’ treatment and prognosis. This study aims to determine the prevalence of different Mycobacteria species from immunocompromised and immunocompetent patients with suspected tuberculosis attending a tertiary care hospital in Kolkata, India....

Utilizing human pluripotent stem cells (hPSCs) in cell-based therapy and drug discovery requires large-scale cell production. However, scaling up conventional adherent cultures presents challenges of maintaining a uniform high quality at low cost. In this regard, suspension cultures are a viable alternative, because they are scalable and do not require adhesion surfaces. 3D culture systems such...

Insufficient myocardial repair after pathological processes contributes to cardiovascular disease, which is a major health concern. Understanding the molecular mechanisms that regulate the proliferation and differentiation of cardiac myocytes will aid in designing therapies for myocardial repair. Models are needed to delineate these molecular mechanisms. Here we report the development of a mode...

The quality of neuronal differentiation and reduction in apoptosis that occurred in two-dimensional (2D) and three-dimensional (3D) culture conditions is compared. PC12 and embryonic stem cells are two commonly utilized cell lines for the study of neuronal regeneration. These cells were induced to neuronally differentiate by adding NGF and retinoic acid respectively. Total neurite length and ex...

Engineering spatial patterning in mammalian cells, employing entirely genetically encoded components, requires solving several problems. These include how to code secreted activator or inhibitor molecules and how to send concentration-dependent signals to neighboring cells, to control gene expression. The Madin-Darby Canine Kidney (MDCK) cell line is a potential engineering scaffold as it forms...

Platelet rich plasma clot- releasate (PRCR) shows significant influence on tissue regeneration in clinical trials. Although, the mechanism of PRCR effect on fibroblast differentiation has been studied on 2D culture system, a detailed investigation is needed to establish the role of PRCR in cell seeded in 3D scaffolds. Therefore, a study was conducted to evaluate the influence of PRCR in fibrobl...

It has long been recognized that body fat distribution and regional adiposity play a major role in the control of metabolic homeostasis. However, the ability to study and compare the cell autonomous regulation and response of adipocytes from different fat depots has been hampered by the difficulty of inducing preadipocytes isolated from the visceral depot to differentiate into mature adipocytes...
