Figure 4From: DNA methylation age of human tissues and cell types Studying the conservation of DNAm age in tissues from great apes. Analysis of two independent data sets involving tissues from great apes. (A,B) Results for data set 72 [27]. A high age correlation (cor = 0.84, error = 10 years) can be observed when studying both chimpanzee heart (colored grey) and human heart tissue (colored turquoise) samples. To facilitate a comparison, I also added the heart tissue data from data set 25 (blue circles). (B) DNAm age is closely related to chronological age (cor = 0.75, error = 3.7) across kidney and liver samples from humans (turquoise) and chimpanzees (grey). (C-F) Results for ape blood samples from data set 73. (C) Highly accurate results (cor = 0.9, error = 1.4) can be observed for blood samples from common chimpanzees (Pan troglodytes; labeled C, colored blue) and bonobos (Pan paniscus; labeled B, colored turquoise). (D) Results for common chimpanzees only. (E) Results for bonobos only. (F) Results for gorillas.Back to article page
