On December 31, 2021, Chen Bin (pseudonym), a student from Hubei University of Economics, successfully completed stem cell collection, bringing hope to a 5-year-old boy to receive hematopoietic transplantation.

He is the 498th donor of hematopoietic stem cells (HSCs) in Central China's Hubei Province, also the 12,582th in the country.

Chen Bin (pseudonym) successfully completed the hematopoietic stem cell collection.

In 2018, Chen provided his blood samples during a voluntary blood donation and became a volunteer HSCs donor.

In August 2021, he got a phone call from the staff of the marrow donor program of the Red Cross Society of China Hubei Branch that he could be a matched marrow donor to a 5-year-old boy with blood disease, when he dedicated himself to study preparing for the national postgraduate entrance examinations.

"People's lives are of the utmost importance. I must donate," Chen said without hesitation.

Then he cooperated with doctors in the preparatory work for HSCs collection while at the same time study for the exam.

Chen Bin (pseudonym) was injected the last mobilization agent.

After finishing a preliminary exam on December 27, 2021, Chen went immediately to the hospital in final preparations for HSCs collection. He needed to get "mobilization" injection for four days, a process through which HSCs could be better mobilized and collected for transplantation.

Chen was awarded for his kind-hearted donation.

Chen never wavered in his determination to donate. He considers himself lucky to be able to save a child's life, and encourages the boy to maintain hope and confidence.

"You gave our child a second chance in life, though we've never met. We'll be eternally grateful to you," reads a handwritten letter from the patient's families to Chen.
