... search for new authentic cancer stem cell markers, the researchers say. "The origins of primary and metastatic tumors are decidedly not the same, and we must broaden our thinking beyond CD133+ cells ...

The molecular profile of cancer stem cells that initiate metastatic colon tumors is significantly different from those responsible for primary tumors, according to new research from a team at Weill ...

... . Both the high- and low-dose treatments led to stabilization or shrinkage of metastatic tumors in about 30 percent of the participants. But the high-dose regimen had significant side effects such as ...

... to metastatic inefficiency arises from the failure of cancerous cells to grow inside invaded organs. Metastatic tumors also show preferential growth in different organs. Hence, the efficiency of the ...

... seek out tumors wherever they may be. "One of the beauties of targeting," she says, " is that we can go after metastatic tumors that are too small to be seen." These targeted gallium corroles are ...

... , the nanoparticle is able to locate primary and hidden metastatic tumor cells and deliver its payload: a fully functioning copy of the P53 tumor suppressor gene. Normal cells have two copies of ...

DENVER, CO and AUCKLAND, NZ (April 21, 2009) - MIS416, a novel microparticle-based immune response modifier, demonstrated the ability to significantly reduce the number and size of metastatic tumor

... the patients studied, 28 (58 percent) had a partial response, a reduction in the size of the metastatic tumor of more than 30 percent by computed tomography. Four patients had a complete response ...

... that might be blocked by drug treatments. In three different ways, the scientists showed that metastatic tumor growth is inhibited if these unusual macrophages are killed. They also showed that even ...
