stem cells

The Director of Barcelona’s Centre for Regenerative Medicine (CMRB), world-famous scientist Juan Carlos Izpisúa, resigned due to the lack of financial and political support from both Spanish and Catalan Governments. Such news was first published by Spanish newspaper ‘El País’ and then confirmed by sources in the research centre. Internationally, Izpisúa is considered to be one of the most esteemed and learned scientists in the field of stem cells. With the Director stepping down, the CMRB could well lose most of its current projects. Indeed, 18 of the 21 projects are the intellectual property of Izpisúa and might no longer be carried out in the Barcelona-based research centre if Izpisúa quit.

Researchers from Barcelona’s Centre for Regenerative Medicine (CMRB), the Catalan capital’s Hospital Clínic and the Salk Institute of California have successfully created three-dimensional renal structures which are virtually indistinguishable from embryonic kidneys. They have started creating kidney cells from human stem cells, and ultimately proven that these newly created cells could aggregate in vitro to form a “micro-kidney”. The team led by Juan Carlos Izpisúa, from the CMRB, said that this scientific breakthrough would facilitate the study of kidney diseases and enable scientists to work on new treatments. He added that this achievement was a great step towards developing therapies based on the use of stem cells.

According to experiments tested on mice, Catalan scientists have affirmed that the stem cells located in the human umbilical chord, which are multipotential and therefore can become different types of cells, can be used to regenerate the tissue affected by a heart attack or a stroke. Until now the only way to recover the damaged tissue was through pharmacological treatment or a heart transplant.
