"We believe induced pluripotent stem (iPS) cells, developed from adult cells, are a critical and rapidly growing segment of the stem cell market. Our laser poration system is designed to allow scientists to introduce new material into the nucleus of cells in order to reprogram the cells, without using the traditional viral agents or chemicals. While traditional methods have a number of drawbacks, our laser poration system, as designed, is anticipated to improve the accuracy and reduce the reprogramming procedure time, which will result in significant savings for laboratories."
