GPT and nonpapillary renal cell carcinoma: Serological (blood urea nitrogen, albumin, alanine aminotransferase, and aspartate transaminase) and hematological (leukocyte, red blood cell, mean corpuscular volume, hemoglobin, mean corpuscular hemoglobin concentration, and platelet) indices were all within the normal range; H&E staining of the major organs (lung, liver, spleen, kidney, and heart) did not show any pathological structural abnormalities, indicating that ccRCC mice could tolerate CISE‐PFD@Gel treatment (Figure S20, Supporting Information).
