    ..Overall, DhiFI hESCs retained advantages of both primed and naive pluripotency and may ultimately represent a more favourable starting point for differentiation towards clinically desired cell types. ..

  3. Heindryckx B, Neupane J, Vandewoestyne M, Christodoulou C, Jackers Y, Gerris J, et al. Mutation-free baby born from a mitochondrial encephalopathy, lactic acidosis and stroke-like syndrome carrier after blastocyst trophectoderm preimplantation genetic diagnosis. Mitochondrion. 2014;18:12-7 pubmed publisher
    ..95). This is the first case of mutation-free baby born from a MELAS patient after TE biopsy and supports the applicability of blastocyst PGD for patients with mtDNA disorders to establish healthy offspring. ..
  4. Neupane J, Vandewoestyne M, Ghimire S, Lu Y, Qian C, Van Coster R, et al. Assessment of nuclear transfer techniques to prevent the transmission of heritable mitochondrial disorders without compromising embryonic development competence in mice. Mitochondrion. 2014;18:27-33 pubmed publisher
    ..We show that NT in the germ line is potent to prevent transmission of heritable mtDNA disorders with the applicability for patients attempting reproduction. ..
  5. Ghimire S, Van der Jeught M, Neupane J, Roost M, Anckaert J, Popovic M, et al. Comparative analysis of naive, primed and ground state pluripotency in mouse embryonic stem cells originating from the same genetic background. Sci Rep. 2018;8:5884 pubmed publisher
    ..We further demonstrate that the differentiation propensity of mESCs to specific germ layers is highly dependent on their respective state of pluripotency. ..

    ..When MOAT reveals no activation deficiency in spermatozoa, AOA still allows for high fertilization and acceptable pregnancy rates. The obstetric and neonatal outcomes after AOA were normal as no malformations were observed. ..
