“Perhaps you know Lesley Wong and William McKinley,” Yamamoto said.
“Like the president,” the young man said. “But call me Will.”
Will stepped forward, a big smile on his face, hand outstretched. Columbia University Medical School had about 640 students spread over four years of training. In general the first two years were primarily spent absorbing the science of medicine with progressively more and more time creatively devoted to introducing students to patients. The third year was the principal clinical year with the major attention devoted to internal medicine and surgery. The fourth year was mostly rotations in various clinical subspecialties combined with electives according to each student’s personal interests. At Columbia the emphasis was on academic medicine. Lesley and Will were fourth-year students in Pia’s class. Both thought they had a new interest in research, which was why they had been assigned to spend a month in Rothman’s lab.
Pia took Will’s outstretched hand and stood up.
“Pia. Grazdani.” She noticed that Will was tall, even a little taller than George, who was above average. Like George, Will had blond, unruly hair.
“You’re George’s friend, right?” Will said.
“George? Yes, of course.”
“Love George, great guy. I often play b-ball with him.”
“I’m Lesley Wong,” the woman said, shaking Pia’s hand in turn.
For a moment there was an awkward silence. Pia briefly eyed the two students, realizing they had to be the students Rothman had briefly mentioned the day before and then never brought up again. He had said something about tasking her to come up with something for them to do, as if she wasn’t going to be busy enough. One way or another it was going to be a burden of sorts.
Lesley and Will eyed Pia back. For their part, they weren’t terribly excited about meeting her either. For them, finding out they had been assigned to Rothman’s lab was the equivalent to being sent someplace in Dante’s inferno. Rothman had the reputation of destroying every student’s sense of self-confidence by making them feel stupid, which they invariably were in comparison to Rothman’s encyclopedic knowledge. And they had heard about Pia as well. She too was known as being over-the-top smart and also strangely detached and had taken an early interest in research in addition to the regular curriculum. For most people being a medical student was demanding enough. Except for being tight with George Wilson, who was one of the more popular students in the class, a mark in her favor, Pia never had had the time or inclination to be particularly friendly with many of her classmates. And all that was on top of the gossip that she and Rothman had something going since she was the only person in the entire medical center that he got along with except for Dr. Yamamoto.
Lesley looked over at Will, but he was staring at Pia. When they’d received their assignment, Lesley had told Will that she’d sat next to Pia in a lab every day for a month the first year but she was sure Pia wouldn’t remember. Lesley hadn’t made up her mind if Pia was extremely focused on her work or just plain rude, although she thought it was the former. As for Will, he was excited to be finally matched with Pia-he’d wanted to be for three and a half years. He’d been sure to introduce himself to every woman in the student body he deemed attractive, but this was the closest he’d come to her.
“Okay. Introductions done,” Yamamoto said. It hadn’t been quite as awkward as he feared, and he was relieved. He could get down to business.
“If it’s okay, we can go to my office. I’d like you to come as well, Pia. There are a couple of things we need to talk over and then we can all go take a look at the organ baths with Dr. Rothman.”
Yamamoto beamed a smile and walked away, the two new students padding closely after him. Pia brought up the rear, reluctant to be leaving her reading but excited at the same time. Even though she had been working there for years, she had never seen the organ baths. Although she had spent more actual time with Dr. Yamamoto than she had with Rothman, she didn’t feel she knew him as well. In her mind he was more complicated than Rothman. She thought of him as a kindly man but knew that in his own way, he was just as demanding as the chief. He suffered fools no more gladly, but his reprimands and corrections were delivered more politely and at lower volume. Pia had gathered from experience that the quieter Yamamoto spoke, the more important it was to listen.
“Okay, guys, find a seat.”
The condition of Yamamoto’s office in comparison with Rothman’s was as different as the men’s personalities. Yamamoto’s looked like a typhoon had passed through it. Books, journals, files, documents, papers lay everywhere, including on each of the two seats in front of the desk. Visitors took it on faith that Yamamoto actually had a desk as every square inch was under paper, including a mountain of academic journals positioned so that a curious passerby couldn’t see whether the doctor was sitting behind his desk or not.
“Just move those papers,” Yamamoto said, as Pia and Lesley Wong gathered them up from the chairs but searched in vain for a free surface on which to put them down. Yamamoto gestured to the floor, a suggestion the women took. He leaned his posterior against the front of the desk and folded his arms. “You could get a chair from the lab,” he suggested to Will.
“No problem,” Will said. “I’ll stand.”
“I thought it appropriate for us to do a small review and go over some introductory material so you people can better appreciate what you’re about to see,” Yamamoto said. “You are in for a treat today. I’ve gotten special dispensation from Dr. Rothman to show you our organ bath program, which has been kept a secret of sorts up until now. It couldn’t have been kept a complete secret as there are too many people working here, and we’re here in a very public medical center. Since the professor and I are close to publication, secrecy is no longer the issue it was since the university has already seen to it that the appropriate patents have been applied for. At the same time, we would prefer that you keep what you see today to yourselves. Deal?”
All three students nodded.
“All right, let’s start at the beginning. But I don’t want to make this a boring monologue so help me out! Somebody tell me what a stem cell is.”
The three students eyed one another. Will spoke up. “In simple terms it’s an undifferentiated immature cell that has the potential of becoming a differentiated mature cell.”
“Right on,” Yamamoto said. “An example is a bone marrow stem that can become an adult blood cell. These cells are often called adult stem cells. What’s a pluripotent stem cell?”
Lesley spoke up: “A stem cell that can turn into any of the three hundred or so types of cells that make up the body of a multicellular organism like a human.”
“Right on again. You guys are making this easy for me.”
Pia felt a wave of impatience wash over her. She was eager to see the organ bath unit. Had it been up to her, she would have preferred to forgo any review session.
“Up until four or five years ago, how were pluripotent stem cells obtained?”
“From blastocysts.” Pia spoke up by reflex. She wanted this little talk over with.
“Right,” Yamamoto said. “Blastocysts from fertilized eggs, meaning very early-stage embryos. Why was that a problem that led to serious delays in stem cell research?”
