• Created using Xara X¹.

• I've drawn this schematic using the sources below as a reference. However, this does of course not mean the image contains no errors. I suggest this image be reviewed by an expert on the field of hematopoiesis. Also anyone else's comments and suggestions are welcome at my en:Wikipedia user talk page.

• I've tried to show all the characteristics of the cells as much as possible. The style in which they're drawn can be compared with how caricatures are drawn. This was not an attempt to draw the cells "photorealistically". For comparison, refer to the erythrocyte that has been drawn in 2 different ways: the style I used for all cells (left) and a different style that shows how the erythrocyte looks through a microscope (right).

• A few things I'm not sure of and that may be incorrect in the diagram:

1) the thrombocyte series can (should?) contain a metamegakaryocyte that comes between the megakaryocyte and thrombocytes. Also a micromegakaryocyte has been identified, but information on these was very rare, so I couldn't include them.

2) Images on the B/N/E Promyelocyte were rare and I'm not sure if I have drawn them correctly. Especially the E. Promyelocyte.

3) I don't know whether all the other cells from the monocytic phagocytosis system (Langerhans cell, Kupffer cell etc.) can also arise from the lymphoid DC. Currently I've also included them in the lymphoid DC.

4) I don't know whether the common myeloid/lymphoid progenitors should have nucleoli. Sources report that they're indistinguishable from small lymphocytes. But they are rapidly dividing cells and therefore (I think) should have nucleoli. Currently, I've drawn them as lymphocytes.

5) Are the common myeloid/lymphoid progenitors a part of the committed progenitor or a part of the stem cells? CLP & CMP are also called common lymphoid/myeloid stem cells, so just the word "progenitor" doesn't rule anything out here...

6) According to sources, the nucleus of a lymphoblast stains reddish-purple, while the images display a blueish-purple nucleus. These images were sometimes on the same page as the text that reported this info (reddish-purple nucleus).

7) Langerhans' cell vs. Langerhans cell. Thefreedictionary.com, On-line Medical Dictionary and Stedman's Medical Dictionary say "Langerhans cell".
