Schematic overview of the patterns of proteoglycan transcription (listed in Fig. 1) defined for the primary cell phenotypes of the healthy hematopoietic system and gathered through a re-elaboration of the combined information accessible through BloodSpot (Normal Human Hematopoiesis– DMAP– accessible at https://servers.binf.ku.dk/bloodspot/) and experimental data reported in the literature. Outlined phenotypic classification is according to the currently adopted one, revised in recent years to better portray the different components of the human hematopoietic system. Virtually no information is currently available about the patterns of proteoglycan expression in isolated common early myeloid and lymphoid progenitors, as well as in the more restricted megakaryocytic-erythrocytic and granulo-monocytic progenitors (grey coding)
