Erythrocytosis denotes the increased red blood cell count per unit of blood, usually associated with increased hemoglobin levels. What is the main pathogenetic link?

		increased erythropoiesis caused by mutations of pluripotent stem cells
		increased erythropoiesis due to increased proliferation of erythrocyte precursors cells independent of erythropoietin
		increased erythropoiesis due to gene mutations of erythropoietin- sensitive receptor
		increased erythropoiesis caused by mutations of mieloid stem cells
		increased erythropoiesis due to increased proliferation of erythrocyte precursors cells dependent of erythropoietin
