“If I had your stem cells and created a heart, liver, lung and an ovary, I could test 10 different drugs at 10 different doses on you and say, ‘Here’s the drug
that will help your Alzheimer’s or Parkinson’s or diabetes,’ ” the lead investigator, Teresa K. Woodruff, said in a report about the research on the Northwestern University website.
Meet Evatar: The Lab Model That Mimics the Female Reproductive System –
By CHRISTINE HAUSERMARCH 30, 2017
Researchers in the United States have created a model of a female reproductive system
that is so close to the real thing it even simulates a menstrual cycle and pregnancy hormones.
“The key here is to have an integrated picture of events occurring in multiple tissues.”
But he said a shortcoming was the use of ovarian tissue from a mouse, which has a reproductive system
controlled by the brain, rather than a monkey, whose reproductive systems are more like humans.
“All of these diseases are hormonally driven, and we really don’t know how to treat them except for surgery,” Joanna E.
Burdette, a researcher with the University of Illinois, said in the Northwestern University report on the research.
The ovary for Evatar uses mouse tissue, and other organs are fashioned from human
tissue obtained from hysterectomy surgery patients for the other organs.
Dr. Jerome F. Strauss III, professor at the obstetrics
and gynecology department at the Virginia Commonwealth University’s School of Medicine, said the research model was a significant step forward because it did not isolate the cells that are important to the function of the uterus.

“If you are worried that your company is lobbying to weaken environmental rules, for example, then it’s really a fabulous opportunity for you to join in with the institutions
and other economic forces making it clear to companies that they can’t get away with it.”
As was the case last year, the topic of climate change will again appear on shareholder proxies this year.
This year, the retirees’ organization wants the company to expand its clawback policy; Verizon’s current policy limits pay recoveries to executives who engaged in “willful misconduct”
that causes significant financial or reputational harm to the company.
“If something goes wrong,” she said, “you want executives to be held accountable and know what the company is doing about it.”
A Caterpillar spokeswoman confirmed that the proposal would be on the proxy this year.
“The whole concept of executive compensation is pay for performance,” said Cornish F. Hitchcock, a lawyer in
Washington who is advising the group of Verizon shareholders proposing the policy change at the company.
Tejal Patel, corporate governance director at Change to Win Investment Group, said her
group put forward a shareholder proposal on clawbacks for this year’s annual meeting.
