Physician-Led Innovation in Birth Tissue Recovery and Regenerative Medicine
Celquest is a physician-led organization dedicated to advancing placental tissue recovery and biologic therapies through ethical donation, clinical expertise, and scientific collaboration. Founded by two physicians specializing in obstetrics, perinatology, and newborn and pediatric medicine, Celquest brings more than 25 years of experience working with birth tissues, including placental tissue, umbilical cord tissue, and both placental-derived and umbilical cord–derived stem cells.
As an FDA-registered and AATB-accredited Tissue Recovery Organization (TRO), Celquest specializes in the ethical recovery and responsible stewardship of human birth tissue, including placenta and umbilical cord, through structured placenta donation programs. These donated tissues support the development of placental tissue allografts and advanced biologic therapies used to treat chronic wounds, diabetic ulcers, severe burns, corneal conditions, and other medical needs requiring advanced healing solutions.
Supported by a multidisciplinary team of quality and compliance professionals, donor coordination leaders, and tissue recovery specialists, Celquest ensures that every stage of the human birth tissue recovery process meets the highest standards of safety, regulatory compliance, donor respect, and tissue quality.
​
In addition to supporting placental tissue allograft development, Celquest contributes to biomedical research and emerging regenerative medicine research initiatives by providing responsibly sourced placenta and umbilical cord–derived biological materials to clinicians, researchers, and biotechnology innovators.
Through physician leadership and a commitment to ethical donation, Celquest is helping advance placental tissue recovery, biologic therapies, and scientific research that improves healing and patient outcomes worldwide.
