Dr. Jose Cibelli is internationally recognized as one of the pioneers in the area of cellular reprogramming using oocyte-driven protocols. Dr. Cibelli together with his colleagues, were responsible for the generation of the world's first transgenic cloned calves, the first stem cells by nuclear transfer in bovine, the first embryonic stem cells by parthenogenesis in primates and the generation of the first line of iPSCs using oocyte factors alone. His work has been published un numerous scientific journals including Science, Nature Biotechnology, Nature Medicine, Nature Methods, PNAS and JAMA. He has testified about his work in public forums sponsored by the US Food and Drug administration, the USA National Academy of Sciences, Canadian House of Commons, the USA Department of Agriculture, the United Nations Commission for Human Rights and the British Royal Society.

First cow embryonic stem cells could lead to healthier, more productive livestock

'“I thought I would never see this happen in my lifetime,” says Jose Cibelli, a developmental biologist at Michigan State University in East Lansing, who was part of a team that attempted to harvest bovine ES cells in the late 1990s. In those efforts and many others since, stem cells from cow embryos would develop into other cell types when grown in a lab dish, meaning that they would quickly lose their “stemmy-ness,” or pluripotency.'

Extension of cell life-span and telomere length in animals cloned from senescent somatic cellsScience
2000 The potential of cloning depends in part on whether the procedure can reverse cellular aging and restore somatic cells to a phenotypically youthful state. Here, we report the birth of six healthy cloned calves derived from populations of senescent donor somatic cells. Nuclear transfer extended the replicative life-span of senescent cells (zero to four population doublings remaining) to greater than 90 population doublings. Early population doubling level complementary DNA-1 (EPC-1, an age-dependent gene) expression in cells from the cloned animals was 3.5- to 5-fold higher than that in cells from age-matched (5 to 10 months old) controls. Southern blot and flow cytometric analyses indicated that the telomeres were also extended beyond those of newborn (
