Cytogenetics and Molecular Genetic Analysis of Chimerism in Marmosets (Callithrix: Primates).

Germ-line chimerism and paternal care in marmosets (Callithrix kuhlii).

The formation of viable genetic chimeras in mammals through the transfer of cells between siblings in utero is rare. Using microsatellite DNA markers, we show here that chimerism in marmoset (Callithrix kuhlii) twins is not limited to blood-derived hematopoietic tissues as was previously described. All somatic tissue types sampled were found to be chimeric. Notably, chimerism was demonstrated t...

Respiratory Animal Models in the Common Marmoset (Callithrix jacchus)

Common marmosets (Callithrix jacchus) are small non-human primates (NHPs) that are often used for respiratory research. Translational animal models of various pulmonary diseases in marmosets have been developed in favor of models in old world monkeys (OWM, e.g., rhesus or cynomolgus monkeys). The marmoset has the size of a rat (350–450 g), is easier to handle, and the husbandry, care, and manag...

Germ-line chimerism and paternal care in marmosets (<i>Callithrix kuhlii</i>)

Matrilineal genetic structure within and among populations of the cooperatively breeding common marmoset, Callithrix jacchus.

Common marmosets are members of the family Callitrichidae, South American primates characterized by highly social group living and cooperative breeding. In this study we analysed 1112 base pairs (bp) of the mitochondrial control region in 59 Callithrix jacchus individuals, sampled mainly from two geographically distinct field sites in N.E. Brazil. Analysis of molecular variation revealed a high...

Marmoset phylogenetics, conservation perspectives, and evolution of the mtDNA control region.

Marmosets (genus Callithrix) are a diverse group of platyrrhine primates with 13-15 purported taxa, many of them considered endangered. Morphological analyses constitute most of the basis for recognition of these forms as distinct taxa. The purpose of this study was to provide a molecular view, based on mitochondrial control region sequences, of the evolutionary history of the marmosets, concom...
