'Figure 1.3.1: The above figure illustrates the three types of action of haematopoietic cytokines 62(Figure taken from Metcalf, D. Blood 2008). (A) Lineage restricted. (B) Action on multiple lineages; broken line shows actions only at high concentrations. (C) Sequential actions; SCF acts on stem and early erythroid progenitors, while EPO acts on more mature precursors. The notion of sequential actions was later found to be incorrect.

 Anmerkungen It is clear to the reader that the figure has been taken from Metcalf. However, the number 62 points to a paper by D. Metcalf that does not contain the figure. However, the article in the journal "Blood" by Metcalf does, such that the reader is not left in the dark. However, it is not clear to the reader that the figure caption has been copied 1-to-1 as well. Sichter (Hindemith)
