Transitional cellcarcinoma (TCC) is a type of cancer that typically occurs in the urinary system: the kidney, urinary bladder, and accessory organs
It is the most common type of bladder cancer and cancer of the ureter, urethra, and urachus; it is the second most common type of kidney cancer.
TCC arises from the transitional epithelium, a tissue lining the inner surface of these hollow orga
bladder tumors are of epithelial origin, the remainder being mesenchymal tumors (Table 21-2). Most epithelial tumors are composed of urothelial (transitional) type cells and are thus interchangeably called urothelial or transitional tumors, but squamous and glandular carcinomas also occur. Here, we discuss the urothelial cell tumors in some detail and only touch on the others.

Figure 1.1. Metabolism of arachidonic acid
Despite the diverse chemical structure of aspirin-like drugs, the antinociceptive effect of NSAIDs is mainly due totheir common property of inhibiting cyclooxygenases involved in the formation of prostanoids. Prostanoids areformed by most cells and act as autocrine and paracrine lipid mediators. They are n
CellLine은 수명의 한계를 크게 가지고 그에 따라 생산량이 적을 수밖에 없다는 점이다. 바로 이러한 점을 해결하기 위한 노력이 불멸화 세포주를 만들게 된 가장 큰 이유일 것이다.
