Transcriptome stability of regulatory T cells in SCT patients. Three-dimensional principal component analysis of the primary Treg transcriptome study and resulting 6 transcriptomes. Closely related transcriptomes are marked by loops. no GVHD d90 indicates Treg transcriptome analyzed on day 90 after SCT of patients with and without developing a GVHD; no GVHD d150, Treg transcriptome analyzed on day 150 after SCT of patients (without) developing a GVHD; aGVHD manif, Treg transcriptome of GVHD patients analyzed at the time point of clinical manifestation of the acute form of GVHD; and cGVHD manif, Treg transcriptome of GVHD patients analyzed at the time point of clinical manifestation of the chronic form of GVHD.
