8:38 a.m.

"Dr. Vee, I'm feeling so much better, I can't tell you." Emma Rosen reached out and caught her physician by the collar of his lab coat, pulling him down and brazenly bussing his cheek. She'd been longing to do this for three weeks but hadn't mustered the nerve until now. "This morning I climbed the stairs to the third floor, twice, up and back without any chest pain. Oy, can you believe? It's a miracle."

Karl Van de Vliet was a couple of inches over six feet, with a trim face and sandy hair that some older patients judged too long for a physician. His English normally was perfect, though sometimes he made a mistake when trying to sound too colloquial. But everyone, young and old adored his retiring Dutch manner and those deep blue eyes that carried some monumental sadness from the past. They also were sure he would soon be recognized worldwide as the miracle worker he was. The prospect of a Nobel didn't actually seem that far‑fetched.

"Emma, please, I begged you to rest." He sighed and checked the dancing electronic pens of her EKG. They were in the basement of the Dorian Institute. Upstairs, the "suites"—nobody called them rooms—were intended to invoke a spa more than a clinic, so most of the heavy‑duty diagnostic equipment was kept in a row of examining rooms down near the subterranean lab. "For another week at least. Why won't you listen? You've been a very naughty girl. I may have to tell your daughter."

He glanced at the seventy‑three‑year‑old woman's readout one last time, made a quick note on his handheld computer, and then laid a thin hand across her brow for a fleeting, subjective temperature check.

She's all but fully recovered, he told himself. It's truly astonishing.

Five weeks earlier, she had come through the front door of the Dorian Institute in a wheelchair pushed by her youngest, a bottle blonde named Shelly. He took one look and scuttled the normal security precautions, the frisk for cameras and recording devices. Emma's low cardiac output had deteriorated to the point that her left leg below the knee was swollen to almost twice its normal size, owing to renal retention of fluid, and she was so short of breath she required oxygen. He hadn't wanted to complicate the clinical trials by taking on another patient at that late date, but she had been referred by a physician friend in the city, begging. How could he turn her away?

He had removed a microscopic amount of bone marrow from her right ankle, extracted the stem cells, applied the hormonal signal that told them to develop into heart muscle, and then injected a thriving cell factory into her heart. Since stem cells could be made to ignore the body's rules to stop replicating after a certain number, they were able to reproduce forever, constantly renewing themselves. The only other cells with that immortal characteristic were cancer cells. In fact, it was as though he had given Emma a new kind of cancer—one that produced cells as healthy as those in a newborn. Today she probably could have run up those stairs.

Although his stem cell technology was going to create a new era in regenerative medicine, he had experienced his share of bumps in the road. Five years earlier, Stanford University had canceled his research project there since the work he had been doing involved the special stem cells in unused fertility‑clinic embryos. The university claimed there had been death threats to its president. The Board of Regents had finally decided with a sham show of remorse, to revoke his funding. They called him in one sunny afternoon in May and pulled the plug. He thanked them and tore up his contract. By that time he had already demonstrated that, using the right chemical signals, stem cells could be coaxed into becoming almost any organ. Inserted into the heart, they became new heart muscle, replacing scars; inserted into the brain, they became neural tissue. No way was he going to be stopped now. They didn't know what they were losing.
