An interesting story about a very popular cultivated variety Neo - regelia cv. Fireball is also mentioned. and Miloslav Studnička.
Induced pluripotent stem cells (iPSC) are undifferentiated cells capable of unlimited self-renewal. By introducing specific transcription factors, any somatic (fully differentiated) cell of the mammalian body can be changed (reprogrammed) into iPSC. The iPSCs are very similar to embryonic stem cells in their molecular and functional properties. By using specific factors, iPSCs can be differentiated into each of the about 200 cell types in the human body. The big advantage of iPSCs is the availability of somatic cells (isolation from blood or skin biopsy). Creation of "tailor made" iPSCs for each patient would allow transplantation of own cells and avoid problems with finding an immunologically compatible donor. and Kateřina Vodičková Kepková, Petr Vodička, Jan Motlík.
V článku je zdůrazněn rozhodující význam školy moderní fyziologie rostlin založené Juliem Sachsem, který byl uveden do experimentálních metod fyziologie Janem Evangelistou Purkyněm jako jeho asistent v Praze. Dále jsou krátce charakterizováni nejdůležitější Sachsovi žáci z jeho rozhodujícího období působení na univerzitě ve Würzburgu a je zdůrazněno trvající působení Sachsových myšlenek až do současného období studia biologie rostlin., The decisive importance of the school of modern plant physiology established by Julius Sachs, who was introduced to the experimental methods of physiology by Jan Evangelista Purkyně as his assistant in Prague, is underscored in this article. The most important disciples of Julius Sachs as a professor in Würzburg are portrayed and the lasting influence of Sachs´s ideas on plant biology is described., Dieter Volkmann., and 5 il.
