<h2>Sammanfattning på Engelska</h2>
<p>Intratumoral heterogeneity is an inherent feature of most human cancers and has profound implications for
cancer therapy. As a result, there is an emergent need to explore previously unmapped mechanisms regulating
distinct subpopulations of tumor cells and to understand their contribution to tumor progression and treatment
response. Aberrant platelet-derived growth factor receptor beta (PDGFRβ) signaling in cancer has motivated the
development of several antagonists currently in clinical use, including imatinib, sunitinib, and sorafenib.
The discovery of a novel ligand for PDGFRβ, platelet-derived growth factor (PDGF)-DD, opened the possibility
of a previously unidentified signaling pathway involved in tumor development. However, the precise function of
PDGF-DD in tumor growth and invasion remains elusive. Here, making use of a newly generated Pdgfd knockout
mouse, we reveal a functionally important malignant cell heterogeneity modulated by PDGF-DD signaling in
pancreatic neuroendocrine tumors (PanNET).</p>
<p>Our analyses demonstrate that tumor growth was delayed in the absence of signaling by PDGF-DD. Surprisingly,
ablation of PDGF-DD did not affect the vasculature or stroma of PanNET; instead, we found that PDGF-DD
stimulated bulk tumor cell proliferation by induction of paracrine mitogenic signaling between heterogeneous
malignant cell clones, some of which expressed PDGFRβ. The presence of a subclonal population of tumor cells
characterized by PDGFRβ expression was further validated in a cohort of human PanNET. In conclusion, we
demonstrate a previously unrecognized heterogeneity in PanNET characterized by signaling through the
PDGF-DD/PDGFRβ axis.</p>
