What is the hormone that causes maturity of the lymphocytes?
Lymphocytes develop in the bone marrow, until they are
differentiated into their specific type - T cell, B cell or Natural
Killer cell. B cells mature into B lymphocytes in the bone marrow,
aided by the hormone interleukin-7. T cells migrate to the thymus,
where they mature into, you guessed it, T l ymphocytes, aided by
several hormones - interleukin-1, interleukin-4, interleukin-6,
thymosin, thymopoietin, and thymulin. I'd be interested to know why
you need to know this.
