ABSTRACT

Disclosed herein are methods and compositions for the identification of teloRNA marks to assess the differentiation status of an individual stem cell or a population of stem cells, to diagnose whether and to what extent a stem cell or stem cell culture has already initiated cell differentiation, and to monitor the differentiation status of an individual stem cell or a stem cell culture during passage. The use of these methods and compositions to monitor the pluripotency and differentiation status of a stem cell or stem cell culture during differentiation enables the identification of undifferentiated and pluripotent stem cells prior to the initiation of differentiation. The methods and compositions can also be used to assess and maintain cell viability; to identify cells or a population of cells that are in a state of poor cell health; and to reduce cell growth or treat a diseased cell including, for example, pre-cancerous cells, cancerous cells, apoptotic cells, aging cells, cells undergoing stress, and otherwise diseased or dysfunctional cells.
