Karyotype of White-Footed Tamarin (): Similarities With Human Karyotype

Abstract

White-footed Tamarin (Saguinus leucopus) is a primate endemic to Colombia whose karyotype is described in this study from a pair of individuals located in the East of Caldas Wild Fauna Rehabilitation Center in Colombia. The blood samples were collected from the femoral vein and anti-coagulated with heparin sodium. The chromosomes obtained by the classic method of culture of lymphocytes as well as Q and G banding. The individuals display 46 chromosomes (2n = 46: 30Bi, 14A); sexual chromosomes XX in female and XY in the male (chimerism 46, XX/46, XY in this last one). An ideogram for the White-footed Tamarin karyotype is proposed. Ample similarities in S. leucopus chromosomes Xy 5 are observed and with human chromosomes Xy 19, respectively. Other partial similarities were demonstrated between chromosomes 1 of both species, S. leucopus 2 and 14 with human 7. The comparison of the size of exonic regions of two genes of S. leucopus and Homo sapiens did not show any difference. El tití gris (Saguinus leucopus) es un primate endémico de Colombia cuyo cariotipo se describe en el presente estudio a partir de una pareja de individuos ubicados en el Centro de Rehabilitación de Fauna Silvestre del Oriente de Caldas, Colombia. Las muestras de sangre fueron recolectadas de la vena femoral y anticoaguladas con heparina de sodio. Los cromosomas se obtuvieron por el método clásico de cultivo de linfocitos y bandeamiento Q y G Los individuos presentan 46 cromosomas (2n = 46: 30Bi, 14A); cromosomas sexuales XX en la hembra y XY en el macho (quimerismo 46,XX/46,XY en este último). Se propone un ideograma para el cariotipo del Tití Gris. Se observan amplias semejanzas en los cromosomas X y 5 de S. leucopus con los cromosomas X y 19 humanos, respectivamente. Otras similitudes parciales se evidenciaron entre los cromosomas 1 de ambas especies, 2 y 14 de S. leucopus con el 7 humano. La comparación del tamaño de regiones exónicas de dos genes de S. leucopus y Homo sapiens no arrojó diferencia.
