This was not the first time that microbiologists experienced problems with agar. A phenomenon called “The Great Plate Count Anomaly” baffled researchers in the early 20th century when they observed that the number of cells seen under a microscope didn’t match the actual number of colonies growing on an agar plate. Investigating this discrepancy, researchers found agar itself to be the culprit: when nutrient broths are heated with agar during boiling, harmful byproducts (hydroperoxide) can form due to the reaction of agar with phosphate minerals contained in the media. Researchers can avoid this by autoclaving agar separately from the nutrient broth, or by reducing the amount of agar used.

除了小分子抑制剂，核酸技术也开始在ACH治疗中得到应用。Ribomic开发的RBM-007，通过限制FGF2和FGFR3激活变体之间的过度相互作用发挥功能。2期临床结果显示，RBM-007的疗效与Vosoritide相近（1.5厘米/年），甚至有一名受试者年增长5厘米，且该试验中包括2周一次的注射频率，是当前在研药物中最长的给药间隔。
