Protocol for Mitochondria Transfer between Mesenchymal Stem Cells and Glioblastoma Stem Cells

Experiment Tags: Mitochondria Transfer, Mesenchymal Stem Cells, Glioblastoma Stem Cells, Cell Interaction, Cell Biology.

Experiment Summary: This protocol facilitates the transfer of mitochondria from mesenchymal stem cells (MSCs) to glioblastoma stem cells (GSCs). This protocol allows for the investigation of the effects of mitochondria on GSC metabolism, proliferation, and response to therapy by isolating mitochondria from MSCs and transferring them to GSCs.

Intraductal Injection of Adenoviral Cre for Temporally Controlled Breast Cancer Modeling in Mice

Experiment Tags: Breast Cancer, Mouse Model, Intraductal Injection, Adenoviral Cre, Temporal Control

Experiment Summary: This protocol outlines a technique for injecting adenoviral Cre (Ad-Cre) intraductally into mice mammary glands to create animal models of breast cancer. By employing cell-type-specific promoters to target mammary epithelial cells (MECs), this strategy enables fine temporal control of cancer induction and cell-type specificity. The process is described in the protocol, which includes creating and caring for floxed mice, monitoring the growth of breast tumors, and providing postoperative care.
