Prof. Vaijayanti Kale

Head SCSCR and Professor SSBS

Research Interests: Stem cell biology, Niche biology, Intercellular communication via extra-cellular vesicles, Signal transduction

Dr. Vaijayanti P. Kale took over as Head, SCSCR, in February 2018, after she retired as Scientist G from the National Centre for Cell Science (NCCS), Pune, after 30 years of service. Her expertise is in the area of stem cell biology with a specific reference to microenvironment-mediated regulation of stem cell fate. She developed and patented a process of creation of Artificial Bone Marrow-like environments (ABME) in vitro. ABME not only has important applications in bone marrow transplantation (BMT) scenario, but also in various stem cell therapies applied for regeneration of tissues. Her recent work demonstrates that mesenchymal stem cells (MSCs) interact with stem cells via intercellular transfer extracellular vesicles (EVs). Most importantly, she showed, for the first time, that the signaling pathways prevailing in the MSCs determine the molecular composition of the EVs secreted by them, thus underscoring the need to assess signaling gamut prevailing in the MSCs before their clinical applications in the regenerative medicine protocols.

She has more than 90 international peer-reviewed publications with an h-index of 20 and i10-index of 37. Her work has been cited in more than 1397 publications. She is on the editorial board of an international journal “Stem Cells and Development”, and Molecular Biotechnology, both published in the USA. During her career at NCCS she has obtained several research grants form DBT, DST, DRDO etc. She serves as a reviewer for several international journals and was also a member of ICMR task force on stem cell research. Currently, she is a member of the Monitoring Committee for CSIR Mission project entitled "Sickle Cell Anemia Mission”. She has reviewed several international and national grant applications. She is also a member of several Institutional Stem Cell Research committees (IC-SCR). Her vision for SCSCR is to develop state-of-art translational as well as fundamental research programs on various types of stem cells.

Dr. Anuradha Vaidya

Associate Professor & Officiating Director Symbiosis School of Biological Sciences (SSBS)

Research Interests: Microenvironment mediated regulation of normal and leukemic hematopoietic stem cells, Deciphering the therapeutic role MSC-derived extracellular vesicles in hematological and neurodegenerative disorders, Cell signalling in adult stem cells.

Dr. Anuradha Vaidya completed Ph.D. from National Centre for Cell Science (NCCS) in January 2011 under the guidance of Dr. Vaijayanti Kale. She joined SSBS in August 2011 and pioneered the establishment of SCSCR in July 2016 with support from the management of Symbiosis. Currently, she is the Deputy Director & Associate Professor of SSBS and holds a dual affiliation – at SSBS and at SCSCR. The primary focus of her research is to understand the microenvironment-mediated regulation of hematopoietic stem cells (HSCs). During her doctoral work, Dr. Vaidya studied the intrinsic as well as the extrinsic mechanisms that affect the regulation of HSCs. She showed that the intracellular activation of p44/42 mitogen-activated protein kinase (MAPK) pathway is crucial for the proliferation of HSCs, whereas the activation of p38 MAPK had an opposite effect on the HSCs. Importantly, she showed that in stem cells, these two pathways are inversely regulated by each other – inhibition of one pathway leads to the activation of the other. She also showed that persistent activation of AKT signalling pathway in the mesenchymal stromal cells (MSCs) affected the proliferation of HSCs co-cultured with them. Through this work, she showed that both the MSCs and HSCs communicated at an intercellular level and that a constitutive activation of the AKT signalling pathway in MSCs has a detrimental effect on the HSCs.

It is now well-known that MSCs exert their effect in a paracrine manner by secreting extracellular vesicles (EVs) that are taken up by HSCs and even other types of cells. Dr. Kale’s group has shown that the biochemical pathways prevailing in the MSCs defines the molecular composition of EVs secreted by them and the cargo inside the EVs defines the outcome of the effector cells. Dr. Vaidya is continuing this line of work, and her team is currently working on understanding whether priming of MSCs with signalling modifiers could expand HSCs for HSC-based therapies and further improve their therapeutic properties for other MSC-based therapies. Such priming strategies could lead to the rejuvenation of HSCs and MSCs, which could have interesting implications in aging-related HSC disorders as well as in leukemia. Besides this work, she is also interested in uncovering the regenerative properties of the MSC secretome, especially the EVs, in the treatment of neurodegenerative diseases. Dr. Vaidya has received a grant from DBT and has published several papers in peer-reviewed journals.

Dr. Ganesh C. Ingavle

Associate Professor, SCSCR & SSBS

Research Interests: Biomaterials and stem cell interactions, Bone and cartilage tissue engineering

Dr. Ganesh Ingavle is an Associate Professor at SCSCR and a recipient of the prestigious Ramalingaswami Re-entry Fellowship award from the Department of Biotechnology (DBT), Govt of India for 2019-2024. He is a biomaterials scientist with a broad research skill base ranging from the development of novel biomaterials and polymer synthesis strategies to their assessment using in vitro cell and in vivo animal models for tissue engineering applications. Dr. Ingavle did his bachelor’s degree in chemistry and a master’s degree in polymer sciences from the University of Pune, India. His doctoral work done at CSIR-NCL focused on developing beaded and monolithic porous (meso, micro and nanoporous) polymers using high internal phase emulsion (HIPE) polymerization for applications such as bio-catalysis, chromatographic materials for separation, and carriers for drugs. After his Ph.D., Dr. Ingavle took up a post-doctoral post in the USA as well as in the UK, and was able to combine his materials science skill base with cell biology and tissue engineering techniques, for the development of biomaterials solutions to address specific healthcare challenges. Within 2 postdoctoral fellowships at the University of Kansas, and the University of California, Davis (UCD), Dr. Ingavle has focused on developing hydrogel-based biomaterials for cartilage and bone tissue regeneration.

Later, he acquired training in animal experimentation skills including minor surgeries (subcutaneous and intramuscular implants) in mice/ rats/rabbits as well as large animal (sheep and horse) surgeries for femoral and large bone defect repairs. In collaboration with Wake Forest Institute of Regenerative Medicine (WFIRM, Wake Forest University, USA), he also worked on projects on High Throughput Screening and 2D and 3D hydrogel matrices for preferential muscle progenitor cell expansion. As a Marie-Curie Experienced Research fellow at the University of Brighton, England, Dr. Ingavle has taken the lead in a number of research areas within the Biomaterials and Medical Device research team. He has led the development of a macroporous polymer- based extracorporeal blood filtration device for the treatment of life- threatening infections. His long-term ambition is to explore a tailor- made polymeric POROUS biomaterial for clinical applications (tissue engineering) and establish a bridge between polymer and biology to understand the structure-property relationship for the final biomedical application. His future research would be aimed at investigating and evaluating tissue-engineering approaches to gain a better understanding of clinically feasible designs.
