Cellular and Molecular Therapeutics

The Cellular and Molecular Therapeutics Laboratory, led by Dr. John F. Tisdale, is working on multiple strategies both in the laboratory and in the clinic to cure sickle cell disease by repairing or replacing the precursor bone marrow cells that give rise to sickled red blood cells.
In addition, strategies to correct the underlying mutation which causes sickle cell disease are being pursued utilizing newly developed gene editing tools, and work in the laboratory to develop methods for efficient editing of hematopoietic stem cells is underway.

Embarazo y donación de cordón umbilical para la anemia de células falciformes Este estudio busca determinar la mejor forma de recolectar, almacenar y manipular sangre de neonatos para ayudar a los investigadores a mejorar los tratamientos futuros para la enfermedad de células falciformes. Para participar en este estudio, debe estar embarazada, debe tener 45 años o menos y debe aceptar donar sangre de cordón umbilical de su recién nacido. Los recién nacidos pueden ser sanos o pueden estar en riesgo de tener enfermedad de células falciformes o rasgo falciforme. Este estudio se lleva a cabo en Bethesda (Maryland).

¿Tiene usted o su hijo enfermedad de células falciformes o beta-talasemia? Los investigadores están probando si una nueva terapia con anticuerpos antes del trasplante de células madre mejora el éxito de dicho trasplante en personas con alto riesgo de presentar complicaciones. Los participantes deben ser mayores de 13 años. El estudio se lleva a cabo en el Centro Clínico de los Institutos Nacionales de la Salud (NIH) en Bethesda (Maryland). Los pacientes que reciben un trasplante de células madre deben vivir a una hora o menos del Centro Clínico de los NIH durante los 3 meses posteriores al trasplante.

Las células madre para el trasplante provienen de un donante totalmente compatible, mayor de 4 años. Los donantes pueden proporcionar muestras de sangre para investigaciones.
