Formation of keratinocyte multilayers on filters under airlifted or submerged culture conditions in medium containing calcium, ascorbic acid, and keratinocyte growth factor.

Three-dimensional (3D) cell culture is a powerful in vitro technique to study the stratification and differentiation of keratinocytes. However, culture conditions, including culture media, supplements, and scaffolds (e.g.

[Liver metastasis from sigmoid colon cancer with peritoneal dissemination showed a complete response to TS-1].

A 64-year-old man with unresectable sigmoid adenocarcinoma due to peritoneal dissemination (P3) and liver metastasis (H2) treated with TS-1, showed a complete response. TS-1 is an oral anticancer drug that produces biochemical modulation. It is composed of tegafur, gimestat and ostat potassium in a molar ratio of 1:0.

[Hepatectomy and intraarterial infusion chemotherapy for liver metastasis from colorectal cancer].

Hepatectomy and intraarterial chemotherapy for liver metastasis from colorectal cancer have been performed in our department. Intraarterial infusion chemotherapy has also been performed for unresectable liver metastasis. One hundred twenty-seven cases of liver metastasis from colorectal cancer were studied.

Irradiation up-regulates CD80 expression through induction of tumour necrosis factor-alpha and CD40 ligand expression on B lymphoma cells.

Previously, we reported that 100 Gy X-ray irradiation followed by 24 hr incubation up-regulates CD80 expression in murine B lymphoma cells, A20-2J. In the present study, we analysed the underlying mechanisms of such up-regulation using A20-HL cells derived from A20-2J cells. Irradiation of A20-HL cells with 100 Gy enhanced CD80 expression.

[A case of hepatocellular carcinoma with portal tumor thrombus effectively treated by arterial infusion chemotherapy with low-dose cisplatin and 5-fluorouracil].

A 69-year-old female with unresectable hepatocellular carcinoma was treated with continuous arterial infusion of low-dose cisplatin (10 mg/body/day) and 5-fluorouracil (250 mg/body/day). The regimen was continued for 5 days then discontinued for 2 days, and repeated for 4 weeks. The portal tumor thrombus almost disappeared and HCC was smaller than before chemotherapy.
