Changes in Retinal Chromatin Allow Animals To Be Nocturnal

Mariam Malik ‘22 Night vision allows nocturnal animals to be active at nighttime and sleep when the sun is out, while diurnal animals are active during the day and sleep at night. However, when both diurnal and nocturnal animals are born, their ocular abilities are equal until a change in the cells of the eye occurs, allowing the animal to see in the dark. Through … Continue reading Changes in Retinal Chromatin Allow Animals To Be Nocturnal

From Colon Cancer Cells to Cancer Stem Cells: The Value of Reprogramming Cells

By Riya Gandhi ‘22 The location of cancer stem cells in tumors has opened the door to the development of a variety of therapeutic applications. These cells are the future of oncology, and scientists still have much to uncover regarding their various uses in medical treatment. While cancer stem cells are treasure chests of opportunity and have wide scientific application, they are difficult to obtain. … Continue reading From Colon Cancer Cells to Cancer Stem Cells: The Value of Reprogramming Cells

Somatic Mutations as Markers for Size and Lifetimes of Blood Stem Cells

By Riya Gandhi ‘22 Despite the importance of hematopoiesis — a process that balances production and destruction of specialized blood cells — in the human body, scientists were unable to quantify the population size and lifetime dynamics that govern the process until now. Researchers from the Wellcome-Trust Sanger Institute, Wellcome-MRC Cambridge Stem Cell Institute, and the University of Cambridge conducted a recent study under principle … Continue reading Somatic Mutations as Markers for Size and Lifetimes of Blood Stem Cells

Stem cells in Dermatology and Anti-aging skin care

By Ellie Teng ‘21 Aging is a biological process that every organism must experience. It’s evident, however, that humans are especially concerned about the physical features associated with aging, which include fine lines and wrinkles on the face and skin. Many anti-aging skin treatments contain ingredients such as stem cells, which are advertised to prevent or reverse the effects of aging. Stem cells are activated … Continue reading Stem cells in Dermatology and Anti-aging skin care

First Human Trial of Stem Cell Therapy for Chronic Spinal Cord Injury

By Anna Tarasova‘19 The therapeutic potential of stem cells has been widely examined by many researchers for more than two decades. Neurodegenerative damage is one of the areas in which the use of multipotent neural precursors (NPCs) has proven particularly useful. Although the use of human-derived NPCs in treating chronic spinal cord injury (SCI) has only been examined in animal models, Phase I and II … Continue reading First Human Trial of Stem Cell Therapy for Chronic Spinal Cord Injury

Restoring Function after Traumatic Brain Injuries

by Julia Newman (’19) Although there is currently no successful treatment for traumatic brain injuries, researchers at the University of California recently tested a new and promising method using human neural stem cells (hNSC), which have been found to be multipotent. Experiments in the past were performed solely on rats using immunosuppressant drugs in order to prevent transplant rejection, but this study found it more … Continue reading Restoring Function after Traumatic Brain Injuries
