Major drawbacks in the procedure developed by the Yale group. Introduction: Scientists at Yale University produced artificially grown tissue-engineered lungs in the laboratory. They anesthetized a group of adult rats, removed their left lung through surgical procedure, and replaced it with artificially grown lungs. The implanted lung tissues were able to exchange gases for about two hours at a similar rate as normal lungs.

Expert Solution & Answer

Explanation of Solution

The Yale group developed a method to transplant artificially grown lungs in animals. The major drawbacks of the procedure are as follows:

1)

The Yale group carried out the experiment on rats. The implanted artificially grown lung was only able to exchange gases at a normal rate for only two hours.

2)

This might not work on humans as organ systems in humans are regulated by several factors.

3)

The experiment was only successful in laboratory conditions. It is not possible to mimic the sterile environment after the implantation.

Conclusion

Artificially grown lungs by Yale group functioned properly for only two hours and that too under sterile laboratory conditions. The procedure may not work on humans.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.) Data Table 1Stage Totals PercentInterphase Mitosis: Prophase Metaphase Anaphase Telophase Cytokinesis Totals 100 100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours.
