Biomedical researchers have long sought ways to repair spinal cord damage with the holy grail of the pursuit being the reconstitution of lost function. In the mid 1990’s with the successful culture of human embryonic stem cells, and about a decade later induced pluripotent stem cells (iPSCs), the field was energized with a potential new approach to replace the lost neurons and glia cells and restoring neural connections. In the decades since that discovery some progress has been made, however many hurdles remain, including establishing a functional synaptic connection between the transpl ..read more

Collectively, retinal degenerative disorders are a major cause of blindness worldwide. For example, one of the most common disorders is age related macular degeneration, which alone affects nearly 200 million globally.
In humans, and other mammals, the loss of the retinal cells is an irreversible process. However, in some non-mammalian vertebrates like frogs and fish, retinal neurons can regenerate. This process is dependent upon Müller glia, which can re-enter the cell cycle and reprogram into neurogenic progenitors upon retinal injury or disease. Progress has been made in understanding ..read more

Since the 1930’s research using human fetal tissue has been used in numerous scientific and medical advances that have saved millions of lives, including the development of vaccines and treatments for diseases. Despite its substantial contribution to medicine and science, significant public debate and misinformation persists surrounding the ethical use of human fetal tissue in biomedical research.
The ISSCR, led by its Public Policy Committee, have been tireless champions and advocates for sound science policy across the globe. This includes advocacy for fetal tissue research and workin ..read more

This November marks the 25th anniversary of the successful isolation and culture of human embryonic stem cells by Jamie Thompson. This breakthrough was a turning point in biomedical research. This discovery provided scientists with a limitless source of human cells to understand human biology and model disease. The discovery also provided a novel pathway to develop tissues and cells that could potentially be used to provide curative diseases like diabetes and Parkinson’s, among others. To date, numerous companies are advancing human embryonic stem cell-based therapies in over 50 approved ..read more

The use of organoids as an experimental system is rapidly advancing in pace and complexity. Derived from pluripotent or tissue stem cells, organoids are three-dimensional, in vitro, structures intended to model functional or developmental aspects of in vivo organs. They are also being used to model complex physiological systems in organ-on-chip devices and in assembloids, the combination of organoids from different tissues. Organoids are especially useful to model and understand aspects of human biology and pathology. This approach has led to much hope, and proof-of-principle findings, that th ..read more

While teeth have evolved over millions of years, scientists are still working to understand how teeth develop, a process formally known as Odontogenesis. Our guests today have developed a new model of mouse tooth development using long-term expandable 3D tooth organoids from postnatal mouse molars and incisors. This novel mouse model provides a valuable tool to study mouse tooth dental epithelial stem cells, dental epithelial-mesenchymal interactions, and differentiation processes, while allowing further elucidation of tooth type-specific features. These models, in combination with human tooth ..read more

Over the last 10 years of Stem Cell Reports, the journal has published nearly 2,000 papers across the breadth of stem cell research. In this special episode of the podcast, we are celebrating the anniversary of the journal by talking with the authors from some of the most highly cited publications in the journal's history.
The guests on this episode of the podcast have collective expertise that makes them the “dream team” of muscle stem cell biology and its application to treat disease.
Akitsu Hotta is a Principal Investigator and Associate Professor in the Department of Clinical ..read more

While advances in stem cell science have led to an increasing number of stem cell-based therapies entering clinical trials, the field is still relatively immature. Thus, these first-in-human trials are using pioneering approaches unique unto themselves, leaving scientists, physicians, and regulators to assess the best approaches for a specific therapy and/or disease. In this episode of the podcast, Martin Pera is joined by physician-scientists Roger Barker and Rajesh Rao who have and are leading stem cell-based trials to discuss some of the criti ..read more

This episode of The Stem Cell Report will explore the scientific applications, advances, and challenges of interspecies chimeras – organisms consisting of cells from at least two different species. The development of interspecies chimeras, most recently advanced by the discovery of pluripotent stem cells and enhancements in genetic editing, have led to greater understanding of fundamental developmental and biological concepts, insight into evolution, and even the development of potential regenerative approaches for human health. Martin Pera will be joined by Drs. Ori Bar-Nur and Jun Wu, along ..read more

In this episode of The Stem Cell Report, sponsored by Bio-Techne, we will explore the modeling of complex human neuropsychiatric diseases such as autism, bipolar disorder, and others using stem cell-based, three-dimensional culture models of the brain and its development. Martin Pera will be joined by Drs. Carol Marchetto and Rusty Gage, experts in the normal and pathological development of the brain. Carol Marchetto is an Assistant Professor in the Anthropology Department at the University of California, San Diego and an adjunct Assistant Professor at the Salk Institute. Rusty Gage is the Vi ..read more
