Infrared Spectroscopy and Imaging in Stem Cells and Aging Research

Abstract

The effect of aging process on stem cell function is crucial because of their critical role in tissue regeneration and repair. The impact of aging on stem cells needs to be understood clearly for the success of clinical application and obtaining desired therapeutic outcome throughout the novel stem cell based therapies. The existing methods used to monitor and characterize the stem cells have some unwanted effects on the properties of stem cells and these methods also do not provide real-time information about cellular conditions. These challenges enforce the usage of nondestructive, rapid, sensitive, high-quality, label-free, cheep, and innovative chemical monitoring methods. In this context, vibrational spectroscopy provides promising alternative to get new information into the field of stem cell biology for chemical analysis, quantification, and imaging of stem cells. Infrared spectroscopy and imaging coupled with chemometric methods can be used as novel and complimentary methods to obtain new insight into stem cell studies for future therapeutic and regenerative medicine.
