It is essential, he said, that the cells contain no residual embryonic stem cells, because when implanted in the body they tend to form tumors called teratomas that consist of a mix of tissue types including hair, skin and teeth.
After adding a drop of tissue lysis buffer, tumor tissue was scraped from the slides, added to a 1.5-μl micro centrifuge tube containing a 200-μl mix of tissue lysis buffer/proteinase K.
You can also consider using tissue paper for the petals, or using a mix of tissue paper and actual petals.
Independently of its putative cell adhesion function, EpCAM strongly supports cell movements and mixing of tissues by a protein kinase C-dependent signaling mechanism.
Mix of diverse tissues used in this study, particularly the inclusion of fruit tissues might have contributed to the variation in size distribution including the observed peak at 19-nt size class and deserves further study.
The gray phenotype was much more heterogeneous and was made up of a mix of degenerating tissues and active intermediate areas.
Finally, a fourth cDNA library was generated from a mix of other tissues, to extend the number of representative ESTs from olive and used for Sanger sequencing (Table 1).
One of the novel miRNAs discovered, ssa-miR 8163, was observed in liver tissue (sample 1 and 6, Table 1), and at low level in the sample from the one day old individual (consisting of a mix of all tissues, sample 13, Table 1) while no ssa-miR 8163 reads were detected at all in any of the other samples.
Five weeks after sowing, for each field-collected individual a mix of leaf tissue from 6 10 sister plants was used for maternal DNA isolation.
Briefly, about 100 mg of tissues were mixed with 1 ml of TRI reagent in 2.0 ml Eppendorf tubes, and the samples allowed to stand for 10 min at room temperature.
