Abstract

Background: Hematopoietic stem cells have been used for over 50 years in the treatment of diverse diseases. Umbilical cord blood (UCB) has proved to be a viable source of hematopoietic stem cells for transplantation purposes. The aim was to report the contribution of the umbilical cord blood bank over the past 9 years, in the treatment of various diseases.

Methods: Since 2005 the number of units of blood from the umbilical cord and their use for transplantation in diverse disease were analyzed. A selection of volunteer pregnant women in labor was performed. Umbilical cord blood was obtained from them, which underwent processing, cryopreservation and validation, as well as compatibility test before using for transplantation.

Results: Ten thousand and ninety nine candidates to donation were assessed, from whom 2481 unit of UCB were collected. Of these, 893 unit were processed and cryopreserved for transplantation. In 65% of cases there was histocompatibility between the cord cell and the receptors. Transplantation was done in 87 patients, 67% had hematologic neoplasias, who have received 140 units of UCB in 102 transplants. This Bank of UCB ranks second in the world in productivity according to the rate of utility of units in transplantation (3.3%).

Conclusions: Our bank of UCB has been able to develop a cell line (hematopoietic stem cells) with international quality standards and has been beneficial for patients served by our institution with need of a transplant mainly in hemato-oncologic patients.

Introducción: las células troncales hematopoyéticas se han empleado por más de 50 años en el tratamiento de diversas enfermedades. La sangre de cordón umbilical es una fuente viable de células troncales hematopoyéticas con fines de trasplante. El objetivo es informar la aportación clínica del banco de células de cordón umbilical (BCCU) en el tratamiento de diversas enfermedades.Métodos: desde 2005 a la fecha se analizó el número de unidades de sangre de cordón umbilical (SCU) y su empleo para el trasplante en diversas enfermedades. Se seleccionaron donadoras embarazadas voluntarias en trabajo de parto de quienes se recolectó SCU, la cual fue sometida a su procesamiento, criopreservación y validación, así como a estudios de compatibilidad previo a su uso para trasplante.Resultados: se evaluaron 10 099 candidatas a donación, de quienes se recolectaron 2481 unidades de SCU, de estas se procesaron y criopreservaron 893 unidades para trasplante. En 65 % de los casos hubo histocompatibilidad entre las células de cordón y el receptor. Se trasplantaron 87 pacientes (67 % neoplasias hematológicas), que recibieron 140 unidades SCU en 102 trasplantes.Conclusiones: nuestro Banco de CCU ha logrado desarrollar una línea celular (troncales hematopoyéticas) con estándares de calidad internacionales, y ha beneficiado a pacientes con necesidad de un trasplante, en especial los padecimientos oncohematológicos.
