adenocarcinoma in APCmin mice‚ so why after miR-34 deletion‚ olfm4 positive stem cell number was increased and tumor incidence was also increased? Their research was working on the colon tumorigenesis‚ but we are working on the small intestine. Also in our model‚ colon tumor is very rare‚ could because of different genetic background. The function of Olfm4 may be also tissue specific. 2. Do these changes caused by the genetic modification‚ but not miR-34 deletion? We also have the floxed control mice

example that can be used to differentiate between various Gram (-) rods of the intestinal tract. Escherichia coli and other enteric bacteria are able to ferment. Lactose fermentation results in a colony color change ranging from pink to purple. Determination of oxygen requirements is a test to determine whether a microbe is an obligate aerobe‚ anaerobe‚ or facultative. The culture is put in a melted 5% glucose TSA. As the media cools it solidifies‚ oxygen is blocked out in the deeper area to create

The unknown bacteria A and bacteria B have to be identified by its genus and species. First both bacteria had to be inoculated into a TSA agar media using the streak plate method. Four quadrants were drawn‚ so that the bacteria could be isolated as much as possible. Each bacteria was inoculated into two different plates‚ so that one could be incubated at 37 degrees Celsius and the other at 25 degrees Celsius. Bacteria B‚ which was incubated at room temperature showed red colonies throughout its media
