Three days later.

Nine in the morning.

Inside the sterile puncture room of Eastern Hospital.

With Zhao Heng's help, the speed of cultivating neural stem cells had significantly accelerated.

Just at seven in the morning, Zhao Heng and Gao Jun went to Yanjing University to retrieve the first batch of already cultivated neural stem cells.

Upon retrieval, Zhao Heng immediately began preparing for Sun Xinxin, and now, the plan was to proceed with the transplantation via the cerebrospinal fluid pathway.

Among all stem cell transplantation methods, the cerebrospinal fluid route is the most direct and effective. This method focuses on stem cell homing and cerebrospinal fluid circulation, which involves lumbar puncture to inject exogenous stem cells into the ventricles and cisterns, allowing them to circulate through the cerebrospinal fluid into damaged brain tissue.

Inside the puncture room, Zhao Heng and Tian Zhen were preparing for the procedure.

Outside the room, separated by a thick transparent glass, only Gao Jun and Sun Xinxin's mother were present.

Although Sun Xinxin was a significant patient, it didn't mean that everyone had to be present during her treatment.

At Eastern Hospital, Sun Xinxin wasn't the only patient who received high attention.

"Director Gao, will Xinxin definitely wake up after this treatment?"

Sun Xinxin's mother looked infinitely lovingly at her daughter lying inside the puncture room, then asked Gao Jun full of hope.

"The hope is very high, this time even Professor Li Hongwei from Yanjing University School of Life Sciences is involved. You can say, nationally, there's no stronger medical collaboration than this."

Gao Jun stated firmly.

"Yes, yes, thank you so much, Director Gao."

Sun Xinxin's mother nodded repeatedly. To treat her daughter, they even brought in a distinguished professor from Yanjing University. What more could she say?

Compared to before at the Mayo Clinic, where she hadn't even met the department head and everything was handled by a resident doctor, the difference was stark.

This only shows that one's own offspring is truly cared for only by one's own family!

"No need to thank me. It was Dr. Zhao who invited Professor Li Hongwei from Yanjing University."

At this moment, Gao Jun also didn't forget to mention Zhao Heng.

"Yes, yes, meeting Dr. Zhao is Xinxin's good fortune."

Sun Xinxin's mother nodded repeatedly.

She meant it sincerely.

Having experienced the Mayo Clinic's treatment and comparing it to now, Sun Xinxin's mother realized that only here, she and her daughter were truly at home.

Moreover, ever since her daughter was transferred here, she had noticed Zhao Heng's efforts.

Inside the puncture room.

Tian Zhen curiously looked at a vial in Zhao Heng's hand, which contained the cultivated neural stem cells.

"Dr. Zhao, are these the neural stem cells cultivated by Professor Li Hongwei from Yanjing University School of Life Sciences?"

Tian Zhen asked curiously.

"Yes."

Zhao Heng nodded.

"This is unique nationwide."

Tian Zhen exclaimed in wonder.

With Zhao Heng, the impossible always seemed to happen.

Just like before, at Eastern Hospital, who would have thought that just because Sun Xinxin needed stem cell therapy, Zhao Heng would bring in Professor Li Hongwei from Yanjing University School of Life Sciences? Nationally, Professor Li Hongwei is at the forefront of stem cell therapy research.

"Dr. Zhao, how did you manage to invite Professor Li Hongwei?"

Tian Zhen asked with great curiosity.

Her curiosity was shared by everyone in the hospital.

Even with Gao Jun's background, inviting Professor Li Hongwei wasn't an easy task.

Let alone Zhao Heng, who was just a grassroots individual before.

"I just attended the professor's public lecture, and after the class, we discussed a bit, and the professor agreed."

Zhao Heng replied calmly.

That's indeed what happened, but if it were someone else, they wouldn't have managed to invite him.

"Just like that?"

Tian Zhen exclaimed in disbelief.

How could someone as top-tier nationally as Professor Li Hongwei be invited so easily?

"Yes, just like that."

Zhao Heng nodded.

"Alright..."

Seeing Zhao Heng's earnest expression, Tian Zhen could only nod.

When miracles occasionally happen to someone, it might excite everyone, but when they become frequent, like Tian Zhen now, people become less excited and more accustomed.

"Dr. Zhao, the sterilization drape is set."

Tian Zhen, working swiftly, quickly got everything ready.

"Alright, let's begin."

Zhao Heng nodded.

The upcoming lumbar puncture posed no difficulty for Zhao Heng, so the process went very smoothly.

Half an hour later, the first batch of neural stem cells, co-cultivated by Professor Li Hongwei and Zhao Heng, had already entered the damaged brain tissue via cerebrospinal fluid circulation. Now, it was time to wait for the neural stem cells to take effect, repairing the damaged brain tissue and finally awakening the long-unresponsive Sun Xinxin.

There were six days left until the two-week deadline.

After completing the procedure, Zhao Heng looked at Sun Xinxin lying on the operating table, still closing her eyes tight, her face pale, and thought.

In six days, everything will become clear.

After the treatment, Sun Xinxin was sent back to the ward.

As soon as Zhao Heng emerged, Sun Xinxin's mother gratefully said to Zhao Heng, "Dr. Zhao, thank you so much for Xinxin's treatment."

"No problem."

Zhao Heng waved his hand.

"Dr. Zhao, will Xinxin wake up this time?"

After expressing her gratitude, Sun Xinxin's mother tentatively asked Zhao Heng nervously.

From her daughter's injury until now, for more than three months, she had experienced too many times of hope leading to disappointment. Now, she didn't dare to have too high expectations for fear of being unable to handle the huge psychological gap if disappointed again.

"Professor Li Hongwei's research on stem cell therapy is top-notch worldwide. If the neural stem cells work and successfully repair the brain tissue, the chances of waking up are quite high."

Zhao Heng said after considering his words.

As a doctor, one can never claim one hundred percent certainty at any time.

However, his statement was already quite confident. He mentioned Professor Li Hongwei because of his top-notch reputation and academic standing.

As for Zhao Heng, although he was already very proficient in cell fate regulation, there were still other advanced techniques from Professor Li Hongwei that he was eager to learn.

"Yes, yes."

Sun Xinxin's mother was very emotional hearing Zhao Heng's response, and hope surged within her.

Upon receiving Zhao Heng's somewhat positive response, Sun Xinxin's mother, filled with excitement, rushed out to take care of her daughter.

After Sun Xinxin's mother left, Gao Jun couldn't help but remark to Zhao Heng, "Xiao Zhao, if this succeeds, our center's reputation will be established."

"It's not easy."

Zhao Heng also said with some emotion.

Starting a venture from nothing is no easy task.

If he hadn't made the connection, getting connected with Professor Li Hongwei would have been completely impossible.
