Abstract (EN)

Adrenal insufficiency is a life-threatening disease, in which adrenocortical cells fail to produce adequate amount of steroid hormones, mostly glucocorticoids (cortisol) and mineralocorticoids (aldosterone). These hormones play an essential role in homeostasis, influencing the level of energy, fluids and salt. Adrenal insufficiency develops due to autoimmune disorders, hereditary factors, infection, metabolic or traumatic conditions, anti-cancer or antifungal therapy etc. Here I demonstrate development of a transplantable bioartificial adrenal cortex as an option for the treatment of adrenal insufficiency
