We further explored the PTN signaling network involved in the intercellular communication network, PTPRZ1 Glioma cells, SDC2 Glioma cells, SDC3 Glioma cells, NCL Glioma cells were used as receivers in the respective hierarchical plots shown in Figure 6C (PTPRZ1), Figure 6D (SDC2), Figure 6E (SDC3), and Figure 6F (NCL), respectively. The gene discussed is PTPRZ1; the disease is central nervous system cancer.
