A method for detecting conjunctival diseases such as conjunctival MALT lymphoma, and an aging biomarker that serves as an indicator of the aging state of a subject are provided. The method for detecting conjunctival diseases comprises a step of comparing a microbial community structure of a microbiota in an ocular surface tissue specimen sampled from a healthy person with a microbial community structure of a microbiota in an ocular surface tissue specimen sampled from a subject to determine that the ocular surface tissue specimen of the subject has an indication of the conjunctival diseases. The aging biomarker a comprises bacterial species which belongs to the Corynebacteriaceae family or the Propionibacteriales family in an ocular surface tissue.

The present invention relates to a method for controlling differentiation of pluripotent stem cells, which method comprises selecting a laminin or a fragment thereof based on binding affinity for the pluripotent stem cells and inducing differentiation of the pluripotent stem cells in the presence of the laminin or a fragment thereof. Here, the binding affinity for cells can be assessed by time-course observation of the survival rate and motility of the cells. According to the present invention, a cell population containing any desired proportion of differentiated cells can be produced from pluripotent stem cells in a simple manner. The cell population obtained by this production method is very useful for cell therapy-based treatment strategies for diseases.
