The thymus gland usually secretes thymic hormones, which are mainly used to induce the development of hematopoietic stem cells into lymphocytes, thereby enhancing the body’s immune capacity and regulating the body’s immune balance, and for the treatment of diseases that occur as a result of immune damage, such as thymic hypoplasia, stroke infection, and severe mixed immune deficiency. The thymic hormones secreted by the thymus gland are important for the healthy development of the human body and the development of the organism. If the thymus hormone secretion is abnormal, the immunity of the human body will be reduced and the endocrine balance will be lost, and other immune diseases will be induced, which may even be life-threatening in serious cases.
