A cell cycle process that modulates the rate or extent of the progression through the preblastoderm mitotic cell cycle. The first nine mitotic division cycles of the insect embryo, during which the dividing nuclei lie deep in the interior of the egg and divide nearly synchronously. This is the first phase of the syncytial period where nuclei divide in a common cytoplasm without cytokinesis. Any process that activates or increases the rate or extent of progression through the preblastoderm mitotic cell cycle. A mitotic cell cycle in which mitosis is completed but cytokinesis does not occur, resulting in a cell containing multiple nuclei each with a chromosomal complement of the original ploidy (usually 2N). Any process that stops, prevents or reduces the rate or extent of progression through the preblastoderm mitotic cell cycle. The process whose specific outcome is the progression of an embryo from its formation until the end of its embryonic life stage. The end of the embryonic stage is organism-specific. For example, for mammals, the process would begin with zygote formation and end with birth. For insects, the process would begin at zygote formation and end with larval hatching. For plant zygotic embryos, this would be from zygote formation to the end of seed dormancy. For plant vegetative embryos, this would be from the initial determination of the cell or group of cells to form an embryo until the point when the embryo becomes independent of the parent plant. Progression through the phases of the mitotic cell cycle, the most common eukaryotic cell cycle, which canonically comprises four successive phases called G1, S, G2, and M and includes replication of the genome and the subsequent segregation of chromosomes into daughter cells. In some variant cell cycles nuclear replication or nuclear division may not be followed by cell division, or G1 and G2 phases may be absent. The eukaryotic cell cycle in which a cell is duplicated without changing ploidy, occurring in the embryo.
