Journal ArticleDOI
Identification of a Neural Stem Cell in the Adult Mammalian Central Nervous System
TL;DR: Evidence is presented that ependymal cells are neural stem cells and a novel process in the response to central nervous system injury is identified, identified in response to spinal cord injury.
Journal ArticleDOI
Generalized potential of adult neural stem cells.
Diana Clarke,Clas B. Johansson,Johannes Wilbertz,Biborka Veress,Erik Nilsson,Helena Karlström,Urban Lendahl,Jonas Frisén +7 more
TL;DR: It is shown that neural stem cells from the adult mouse brain can contribute to the formation of chimeric chick and mouse embryos and give rise to cells of all germ layers, demonstrating that an adult neural stem cell has a very broad developmental capacity.
Journal ArticleDOI
Identification of human chromosomes by DNA-binding fluorescent agents
Torbjörn Caspersson,Torbjörn Caspersson,Lore Zech,Lore Zech,Clas B. Johansson,Clas B. Johansson,E.J. Modest,E.J. Modest +7 more
TL;DR: A convenient measuring technique has been developed for the rapid and accurate recording of fluorescence patterns in human metaphase chromosomes that should be particularly valuable for the identification of chromosomes 4–5 and the individual types in the 6–12 group.
Journal ArticleDOI
Differential binding of alkylating fluorochromes in human chromosomes.
TL;DR: Human metaphase chromosomes from blood cultures, treated with quinacrine mustard, show a banded pattern of fluorescence, which in the chromosomes with the most strongly fluorescent regions (3, 13–15 and Y) was found to be constant and reproducible.
Journal ArticleDOI
Evidence for neurogenesis in the adult mammalian substantia nigra
Ming Zhao,Stefan Momma,Kioumars Delfani,Marie Carlén,Robert Cassidy,Clas B. Johansson,Hjalmar Brismar,Oleg Shupliakov,Jonas Frisén,Ann Marie Janson +9 more
TL;DR: Evidence for the generation of dopaminergic projection neurons of the type that are lost in Parkinson's disease from stem cells in the adult rodent brain is provided and it is shown that the rate of neurogenesis is increased after a lesion.
