Bio-luminescent imaging
Hair growth has been on ongoing research topic It is thought that stem cells can regenerate hair follicles when injected into animals and humans. However, this process has not been imaged very clearly. A group of scientists from Kyungpook National University School of Medicine, Daegu, Republic of Korea have used bioluminescent imaging to track injected stem cells and determine whether the stem cells become hair follicles.
Bio-luminescent imaging uses luciferase with luciferin to determine the location of cells. It has also been used with other methods to determine the presence of a gene, reporter molecule or enzyme activity.
